CRABRO VESTITUS. 131 



spots ; the wings hyaline and iridescent, the nervines and 

 tegulae piceous ; the anterior and intermediate femora beneath, 

 the anterior tibise in front, a stain at the knee of the interme- 

 diate pair, and a ring at the base of the posterior ones, yellow ; 

 the tarsi piceous. The abdomen smooth, shining, and sub- 

 clavate. 



No locality is known for this species : it is unique in the 

 collection of Mr. Westwood. 



9. Crabro vestitus. 

 C. niger, flavo-maculatus ; metathorace rugoso, capite thoraceque 

 subtus pilis longis vestitis. 



Male. Length 4 lines. — Black ; head and thorax subopake, 

 closely and strongly punctured ; the face canaliculated, smooth 

 and shining, the inner orbits of the eyes and the clypeus densely- 

 covered with silvery pubescence ; the cheeks have also a thin 

 silvery pubescence, that on the vertex is fuscous ; the scape 

 yellow, with a dark stain behind; the flagellum fulvous beneath; 

 the mandibles ferruginous at their apex. Thorax : an interrupted 

 line on the collar, and the tubercles, yellow ; the subcordiform 

 space at the base of the metathorax longitudinally grooved, 

 beneath which it is coarsely and transversely striated ; the 

 wings slightly coloured, the nervures and tegulse rufo-testa- 

 ceous; the sides and the mesosternum covered with long griseous 

 pubescence, that on the disk of the thorax is short and fuscous; 

 the anterior femora yellow, with a rufo-piceous stain behind at 

 their base ; the intermediate pair yellow above and at their 

 apex beneath ; the tibiae and tarsi yellow, the former with more 

 or less of a rufo-piceous stain beneath, the claw-joint of the 

 tarsi rufo-piceous ; the posterior femora with short silvery pu- 

 bescence within, the tibiae slightly spinose. Abdomen with five 

 yellow bands, the second slightly interrupted ; sometimes the 

 first also, the third rarely so. 



I believe this to be undescribed. 1 captured three specimens 

 of the male in Yorkshire : the female I do not know. 



** Antenna and tarsi simple. Base of the metathorax smooth 

 and shining. (Sp. 10-21.) 



10. Crabro leucostoma. 

 C. niger; antennarum scapo tantum a latere flavo signato ; meta- 

 thorace Isevi.
