Described from 4 males, 5 females. The sexes are so 

 unlike that no one, without breeding them, would suspect 

 their identity. They are also anomalous in some other 

 respects. Segment 1 is narrowed a little towards the 

 apex, as in Sect. IV., but still distinctly truncated, as in 

 Sect. I. Segment 2 is less rugulose than 1, in some 

 specimens almost as smooth as the following segments ; 

 it is canaliculated in the middle, and furnished with two 

 arcuate impressions converging forwards, as in Sect. III. ; 

 the space enclosed between the lines is raised and 

 shining ; but this structure is irregular and indistinct. In 

 the ? the abdomen is testaceous; segment 1 at the base, 

 and 2—5 more narrowly, fuscous. The cariniform edge 

 of the belly and the subulated valves of the terebra are 

 black. 



Gregarious ; bred in some numbers by Bignell from 

 the larvae of Melitmi aurima, Eott., taken in North Devon. 

 The white cocoons are enclosed in a common web of 

 cottony texture.
