S ? . Geiiiil ])rocess large, triangular, nearly reaching to tip ot'iiiiilcr. Eye-lashes 

 heavy. Antenna clubbed ; hook suddenly narrowed ; end-segment conical, at 

 least three times as long as basally broad. Abdominal spines weak ; anal tuft 

 truncate, preceding segments with side-tufts. Hinder edge of merum of midcoxa 

 rounded, neither angulate nor cariniform ; tibiae spinose ; foretibia ending in a 

 thorn, a lateral row of heavy spines, the basal ones the shortest ; spurs of mid- 

 and hindtibiae unequal, longer ones e(pinHiug or surpassing in length second 

 tarsal segment ; no comb to mid- and hindtarsus ; ventral lobes of parouychium 

 very small : jiulvillus present. R- of hindwing central ; W and M^ rather close 

 together ; D- transverse, slightly concave, D^ oblique, lower angle of cell little 

 produced. 



S- Tenth tergite and steruite simple, of the same type as in Mueroglossum. 

 Clasper without friction-scales ; harpe vestigial. Penis-sheath with a horizontal, 

 apical, pointed ])rocess, directed dextro-laterad. 



Larva: head small, not grauulose, but hairy; a pale dorso-lateral line, and 

 another veutro-lateral, at least in early stages, with these are connected oliliipie 

 bands running in the same direction as iu Pholus, dorso-frontal — ventro-distal ; 

 horn short, or in later stages vestigial. 



Chrysalis slender, glossy ; two frontal tubercles ; mesonotum with transverse, 

 mesially interrni)ted ridge ; abdominal segments with large punctures at base, 

 last segments punctured nearly all over ; cremaster long, slender, ending in 

 two points.

Five species. 



Since the genus as conceived by us contains material closely related inter se 

 ill pattern and structure, and is sharply defined, we do not see the necessity of 

 dividing the few species into several genera. On the contrary, we think it highly 

 opportune to keep the five species under one generic head and thus impress upon 

 the student the facts (1) that we have here, as in the case of Haemorrhayia, a 

 development common to the Northern temperate regions (except the eastern parts 

 of the Fiilaearctic Regions, where as yet no representative has beeu found), and 

 (2) that the bombiform Jhcojmciata is a derivation from a ^a«raf-like insect, 

 owing its similarity with Haetnorrhagia to mimicking the same model. 



If one separates the Palaearctic proserphia from the Nearctic forms, it becomes 

 necessary to further divide these, and there would then be even justification for 

 keeping each single species in a genus of its own. In this case a generic term 

 will have to be invented Hot juan/tu, which differs essentially from ya«/'rtt' in the 

 larval state. Everybody may please himself in this matter, but we state with
