This study was aimed to elucidate the physiological function of a pair of protuberances like bifurcated horns developed on the anterior part of pupa in Coboldia fuscipes (Diptera: Scatopsidae), a pest on the oyster mushroom. In the morphological characteristics, larvae had a pair of 0.04 mm long microspines at their second body segment. Pupae had a pair of protuberances like bifurcated horns of 0.55 mm long on the anterior part and six pairs of spines, 0.12 mm long, at the posterior part of the abdomen. The microspines-removed 4th instar C. fuscipes larvae developed into pupae without a pair of the protuberances. After emergence, however, the adults have a pair of antenna normal regardless of with or without the protuberances. As ecological characteristics at the pupation, the pupa without a pair of the protuberances have a tendency to pupate outside the medium. However, development characteristics of the microspines-removed larvae were very similar to those of control larvae. In the result of microscopic observation, a pair of the protuberances was connected wit six pairs of spines by lateral longitudinal trunck and formed a tracheal system. In conclusion, this results implicates that the protuberances have an important role as a respiratory horn during the pupal period.

Amyotrophic lateral sclerosis (ALS) is one of the major neurodegenerative diseases that involves degeneration at all levels of the motor system- from the cortex to the anterior horn of the spinal cord. Patients with ALS often have difficulty of ambulation for dental treatment though they have poor oral hygiene state. General anesthesia may cause respiratory problem due to its high sensitivity to muscle relaxant and weakened upper airway. In this case report, 38-year-old female patient with ALS required many dental treatments. Conscious sedation with intravenous target controlled infusion method was successfully employed and patient was discharged without any complications.

The egg capsule of Hongeo koreana is newly described based on two egg capsules extracted from the uterus of a female collected near the type locality, the southwestern coast of the Korean Peninsula. The egg capsule of H. koreana has the following characters: medium sized, measuring 124.5~133.7 mm in total length including horns, 102.8~109.4 mm in length excluding horns, and 41.0~42.2 mm in maximum width; asymmetrical, with the egg capsule more convex ventrally in lateral view; the surface relatively smooth, with longitudinal striations distinct, and covered with masses of sticky silky fibers; anterior and posterior aprons distinct; all four horns short, tube-like in shape, elliptical in cross section, anterior horns recurved inwardly; respiratory fissure present at tip of each of the four horns. The color of the fresh capsule is bright brown.
