282 GENUS PHYLLOTOMA. 



E. cinctus, but it wants the pale black stripe, and over 

 the legs there is only one row, but of larger black 

 spots. It is also smaller and more slender. 



It lives on Rubus idceus, in the stems of which it 

 bores to pass the pupal state, boring into the pith to a 

 depth of from one to a foot and a half. 



Bouche bred Ichneumon bituberculatus from it. 



In Britain E. perla appears to be rare. I have 

 taken it at Rannoch. Mr. Bridgman takes it at Nor- 

 wich, Mr. Dale at Glanvilles' Wootton, Stephens records 

 it from Hertford, and Mr. T. Wilson has captured it 

 near York. 



Genus PHYLLOTOMA. 



Phyllotoma, Fall., Mon. Tenth. Suec., 1829. 

 Heterarthus, Ste., 111., vii, 94. 



Wings with two radial and three cubital cellules, the first and second 

 of the latter receiving each a recurrent nervure ; the second cubital as 

 long, if not longer, than the first ; transverse radial, and recurrent 

 nervures received not far from middle of cellules; transverse basal 

 nervure in part received in front of stigma ; transverse median usually 

 beyond the middle. Lanceolate cellule with an oblique cross nervure ; 

 there are no median cellules in hind wings ; the accessory nervure is 

 longly appendiculated. Stigma large. 



Antenna filiform, ten to fifteen -jointed, the third joint longer than 

 fourth. 



Head broad compared to length, concave behind, the front slightly 

 projecting, but retreating between the antennas and the eyes, which 

 are prominent, oval, and placed at a distance from the mandibles. 

 Clypeus truncated. Mandibles weak, sharply pointed at the apex, a 

 slight indentation in the middle. Palpi long, maxillary with the first 

 joint small, second more than double its length, but a little shorter 

 than the third, the fourth is the longest, the sixth a little longer than 

 the fifth. Labial palpi have the first joint a little shorter than the 

 second, the three succeeding of nearly equal length, the last thinner. 



The legs are longish, especially the hinder pair ; the tarsi have no 

 patellae, the claws bifid, somewhat dilated at the base. 



The abdomen is broad, scarcely rounded on the back ; the blotch is 

 distinct ; the saw short and broad. 



The head and thorax are black, usually more or less 

 marked with white; the abdomen is either black
