134 THE entomologist's RECORD. 



on either side is quite free, except that it is kept attached to the nieso- 

 thorax by the first spiracle. The antennre are free nearly all their 

 length froni the wings, but are attached to the legs, except just at the 

 base of the first pair. The head remains attached to the maxilla? and 

 first legs. 



The posterior end of the pupa is the 9th (with 10th ?) abdominal 

 segment, forming a rounded shield ; in front of it ventrally is a deep 

 hollow, whose anterior margin is the posterior border of the -Tth 

 abdominal segment. A hand lens hardly reveals any hairs. 



The pupa mounted and viewed transparently, presents hardly a 

 point by which it can be dift'erentiated from that of liutiiicia phlaeas. 

 The ribbed network is almost of the same pattern. The rosettes have 

 their margins more definitely divided into leaflets, generally trefoil, but 

 quadrifoliate, etc., with considerable variation, B. pldaean shows only 

 traces of such division. //. rinianreas is more like H. (Jorilis, but they 

 are more irregular in shape in that species. 



The "umbrella" — or "fungus" — hairs are very like those of 

 phlaeas, perhaps a little larger, an upright solid looking stem, ending 

 in a rather flat expanded flower-like cup, supported by irregular ribs 

 ending in projecting points at the margin. In dispar, the hollow of 

 the cup extends downwards to the base, there being no separate stem, 

 the expansion of the cup beginning gradually at the base, instead of 

 suddenly at the top of a stem. Vrri/ain-eai' is of the same type as ilispar. 

 Aniplii(Jai)uis is different, there is no cup, but the top is branched like 

 antlers, generally four. Like p/dacas there is a definite dorsal head- 

 piece of much the same size and shape, and the structures otherwise 

 are practically indistinguishable, it has a cremaster of short anchor- 

 shaped hooks, just like phlaeas. 



On the wings, which are perhaps most easily compared, the rib- 

 netting is of a slightly larger and bolder character than in phlaeas. 



There being only one specimen of dorilis, its variations can only be 

 guessed, but as to phlaeas, some pup* are of nearly uniform ochreous 

 tint, and others vary into black dots and spots, quite approaching 

 this dorilis. 



The flights of lenticles round the spiracles seem to be rather denser, 

 of larger lenticles than in jddaeas, and on the 2nd abdominal segment, 

 they are marshalled mto close rows by evanescent lines of ribbing 

 passing between them.

Fig. 1. — Thorax, wing and first four abdominal segments of right side, x 10. 

 The shade near the front of prothorax is the dorsal headpiece, which is attached to 

 the prothorax, but has here been doubled beneath it. 



This shows the dark spotting of the pupa. 



Fig. 2 shows a central portion of Fig. 1, x 2.5. It shows the different pattern 

 of netting on the body and on the wings, the latter being without hairs, lenticles, 

 or rosettes. 



It shows also the special pattern of netting across the origin of the wings, both 

 of meso- and meta-thorax. 



Fig. 3 is a portion of the margin of an abdominal segment, x 200, showing 

 the umbrella- (fungus-, trumpet-) hairs, several lenticles and the rosettes at the 

 branchings of the netting.
