British Species of Allotrince. 69 



ventral surface of the abdomen rufous ; wings almost 

 hyaline ; the nervures dark testaceous. Antennae three- 

 fourths of the length of the body, without a defined club, 

 the joints becoming gradually thickened from the second 

 joint to the apex ; the third joint about one-fourth longer 

 than the fourth ; the fifth and sixth subequal ; the other 

 joints moniliform, longer than broad ; the last conical at 

 apex, one-half longer than the penultimate ; the basal joints 

 piceous on the lower side. Prothorax in the middle in front 

 raised above the mesonotum, and clearly margined above 

 and at the sides, the top being semi-circular ; at the sides 

 of the pronotum is a thick tuft of white hair. Scutellum 

 large, the apex rugosely punctured ; the cup large, oval, its 

 apex projecting, and with a shallow transverse, oval fovea ; 

 the basal foveae large, deep, wider than long, distinctly 

 separated ; there is a well marked transverse furrow in front 

 of them. Metanotum excavated deeply in the centre, with- 

 out keels, the apex punctured ; the metapleurai densely 

 covered with white hair. Abdomen a little longer than the 

 thorax, compressed ; the hair fringe gray, narrow, distinct ; 

 the apex and ventral surface widely rufous. Radial cellule 

 elongate, twice longer than wide ; completely closed ; the 

 second abscissa of radius distinctly curved, three-fourths of 

 the length of the third, which is only slightly curved at the 

 apex ; the cubitus complete. 



The $ has the antennae somewhat more than twice the 

 length of the body ; the third joint curved and a little longer 

 than the fourth. 



This is a true Eucoila, intermediate as regards most 

 structural points between Eucoila and PsicJiacra, Foerster, 



Length (? 2, ? nearly 3 mm.
