Male. Tilis species is quite similar to affinis, also in the shape 

 of upper and lower forceps, which are only a little more robust. The 

 specific difference lies in the shape of the præhypopygial segment 

 and the hypopygium; the præhypopygial segment has at the hind 

 margin on each side a round protiiberance, and the hypopygium has 

 a similar protuberance on each side, so that there are four pro- 

 tuberances placed squarely; the protuberances are rather densely 

 haired, especially the upper. 



Female. Quite similar to the female of affinis and scarcely to 

 distinguish with certainty. 



Length 7 — 8 mm. 



A. mamillata has hitherto been taken only at Valby near Copen- 

 hagen and at Tisvilde; my specimens are bred from a Hyponomeuta; 

 it is no doubt common where Hyponomeuta is found. The species is 

 known as parasitic on H. cognatella and probably also padella and 

 other species of the genus. Nielsen mentions 1. c. that the larvæ 

 occur in webs of Hyponomeuta and eat the pupæ, boring in at one 

 end and out of the other, and thus destroying many pupæ. 



Geographical distribution: — Europe down into France; towards 

 the north to southern Sweden (Ringdahl). 



28. Angiometopa B. B. 



Medium sized grey species with striped thorax and black spots 

 on abdomen which are fixed, not shifting according to view. The 

 genus is nearly related to Agria. Head as in this genus; frons in male 

 half as broad as the eye, in female broader, somewhat protruding. 

 Jowls about half as broad as the height of the eye. Bristles as in 

 Agria. Occiput with all black hairs. Frontal bristles descending 

 to insertion of antennæ, the rows not diverging below; in female 

 an outwards directed bristle above. Cheeks with fme hairs. Vibrissæ 

 slightly ascending, the vibrissal ridges broad, much diverging 

 and somewhat converging below. Epistoma somewhat broad, not
