be very closely allied. The habit of the imago in sometimes laying 

 its eggs scattered, at others in little groups, is noteworthy in a super- 

 family where egg-laying is pretty constant in the same species. The 

 larva, structurally, appears to be quite an exception to the other 

 Lachneid larvae so far examined, in that the anterior trapezoidals i on 

 the abdominal segments are considerably smaller than the posterior ii, 

 although on the meso- and metathorax the reverse is the case, the 

 anterior i being much larger than the posterior ii. There is a small 

 supraspiracular, and of the two subspiraculars iv and v, the former is 

 much larger than the latter on the abdominal segments, but situated 

 close together, and suggest strongly the process by which they have 

 coalesced on the thoracic segments, a feature that is very characteristic 

 also on the abdominal segments of most other Lachneid larva?. All 

 the tubercles have a wart-like structure and bear many hairs. The 

 pupa is enclosed in a small tough cocoon, not of the " eggar," nor of 

 the loose Eutrichid type, and in this one peculiarity bears a resemb- 

 lance to Trichiura crataegi. Sexual dimorphism is well marked as in 

 all Lachneid moths, but there is no ? anal tuft as in Trichiura and 

 Lachneis, and the appearance of our only European species in mid- 

 winter is sufficiently remarkable to notice.

Stephens' diagnosis of the genus (lllus. Haust., ii., p. 43) reads as 

 follows : 



Poecilocampa, mihi. Palpi extremely minute, subglobose, enveloped in slender 

 elongate hairs ; maxillae obsolete. Antennae densely bipectinated in the males, the 

 pectinations scarcely decreasing towards the apex, strongly serrated in the females ;
