VIII. General Summary. 



(1) 111 u iicsi of Boinhvs derhaineUus received I'ruiii Kent 

 ill July 1918 were the following insects : — 



(a) larvae of the Tachinid Brachycoma devia, which pu- 



pated at the end of July, the adults emerging in 

 May, 1919. 



(b) puparia of the Phorid Aphiochaeta rata, from which 



adults and a Braconid {Ortliostigina pmniluni) 

 emerged in August, 1918. 



(c) larvae of the Cryptophagid Antherophayus pallens, 



which passed the winter in cells excavated in 

 sawdust, not pupating till late in April or early 

 in May, 1919. The pupal stage occupied about 

 12 days. 

 {d) larvae of the Nitidulid Epuraea depressa. These 

 pupated about the middle of August and adults 

 emerged at the end of the month. The pupal 

 stage lasted 8-10 days, and the adults remained 

 in the pupal cells 11 or 12 days. 



(2) The larva of Ejniniea depressa is described for the 

 first time. Only one other species {E. obsoleta) of the 

 genus seems to have been described in the larval state. 

 In both species the larvae are furnished with numerous 

 longitudinal series of flattened, truncated, spatulate hairs, 

 rising from tubercles on the dorsal surface. The larva of 

 E. depressa has 4 ocelli on either side of the head ; 4-seg- 

 mented antennae with an appendage on the 3rd segment ; 

 mandibles furnished with a remarkable group of processes; 

 maxillary palpi 4-segmented ; labial palpi 1-scgmented ; 

 spiracles pedunculate and biforous, one pair betweeu pro- 

 and meso-thorax, and 8 other pairs on abdominal segments 

 1-8 respectively. 



(3) Larvae of E. depressa, after treatment with caustic 

 potash, were fouud to have in the gut mineral particles, 

 spores, and fragments of fungus-hyphac, 



(4) The pupa of E. depressa is armed with spines situated 

 on the head and prothorax, at the femoro-tibial joints of 

 all the legs, and arranged in two longitudinal series along 

 either side of the abdomen.
