HOPLOCAMPA CRAT-SJGI. 261 



Readily known from the other black species by the 

 testaceous pleurse. 



The only specimen I have seen was taken by Mr. 

 Ed. Parfitt in Devonshire. Mr. Parfitt believes that 

 it was bred from pea-shaped, woolly-haired galls found 

 on a species of willow. There is nothing anomalous in 

 a Hoplocampa being a gallmaker, for Giraud has 

 described* a species (H. xylostei) which forms galls on 

 the young branches of Lonicera xylosteum, but I am 

 inclined to believe that a mistake has been made in the 

 labelling of Mr. Parfitt's species, for the galls which 

 that gentleman sent me as being those of the Hoplo- 

 campa were undoubtedly those of a Nematus. 



5. HOPLOCAMPA CRAT^GI. 



Tenthredo cratcegi, Klug, Berl. Mag., viii, 54, 18; Htg., Blattw., 



278, 41. 

 Hoplocampa cratcegi, Thorns., Opus., 277, 3 ; Hym. Scand., i, 



201, 4; Andre, Species, i, 326; Cat., 



41,* 5. 



Pale reddish-yellow ; antennae from the second segment, posterior 

 tarsi and the greater part of posterior tibiae, fuscous ; a small mark on 

 front of mesonotum, a larger one on either side, the metanotum and base 

 of abdomen black. Wings hyaline, costa, stigma and nervures pale 

 reddish-yellow. 



The < has the metanotum and the greater part of the dorsum of 

 abdomen black, while the legs are entirely yellowish. 



Length 2? lines. 



The antennas in this species and in alpina are longer 

 than in ferruginea, while the colour is paler, the meso- 

 notum is smooth and shining, and the stigma is uni- 

 colorous. Cratcegi is of a redder tint than alpina, the 

 colour not being so deluted ; the mesonotum shows a 

 trace of puncturing; the mesonotum is always distinctly 

 marked with black, as is also the base of the abdo- 

 men, the wings more iridescent, the nervures distinctly 

 traced, while the antennas and posterior tarsi and 

 apical half of tibias are distinctly fuscous. Occasion-
