1152 Insects. 



This species, as I have already observed, is parasitic upon Saro- 

 poda and Megachile, and this year I observed it plentiful about the 

 burrows of a colony of Anthophora, which they were entering appa- 

 rently upon the most friendly terms with the rightful owners. The 

 Ccelioxys inermis of Kirby is an injured specimen of the male of this 

 insect, the thorax having been crushed, and the spines hidden by the 

 metathorax : the original specimen still exists in the cabinet of the 

 Entomological Society. 



Sp. 2. Ccelioxys Vectis, Curtis. 



Female. — Length, 6 — 7 lines. Black, coarsely punctured on the 

 head and thorax. Head as wide as the thorax. Clypeus covered with 

 a very short fine cinereous pubescence, a longer pale pubescence above 

 extending to the base of the antennae ; a patch of white pubescence 

 beneath the wings. Scutellum bidentate. The anterior femora have a 

 white patch behind, and the coxae have an obtuse tooth ; the posterior 

 trochanters and femora have a short fringe behind of pale yellowish 

 hairs. Abdomen conical, the base of the fourth and fifth segments 

 and the whole of the sixth finely punctured, the other portions with 

 deep scattered punctures, the basal segment has a white pubescent 

 spot on each side, and the four following have similarly coloured late- 

 ral spots, pointed within; beneath, the first segment has a white patch 

 in the centre of the margin, and the rest a white marginal fringe. 



Male. — Length, 5j — 6 lines. Black. Head and thorax coarsely 

 punctured. Face covered with hoary pubescence, very thinly scat- 

 tered on the vertex, and also upon the disk of the thorax ; the pubes- 

 cence is thicker on the sides and beneath. The anterior coxae are 

 toothed, and the scutellum is bidentate. Abdomen with deep punc- 

 tures, the white patches as in the female, a minute tooth at the extreme 

 lateral margins of the fifth segment, another at the base of the sixth, 

 with two stout ones at the apex, which are bidentate at the tips, the 

 upper tooth minute. 



This species is local. Mr. Curtis first took it in the Isle of Wight. 

 I have captured a single specimen in Hampshire ; and my friend Mr. 

 S. Stevens this year took it at Little Hampton, Sussex. 



Sp. 3. Ccelioxys rufescens, Serv. 9 St. Fargeau ? 



Female. — Length, 6 — 7 lines. Black. Head and thorax closely 

 punctured : the face, and the thorax on the sides and beneath clothed 

 with a reddish yellow pubescence. The anterior femora have a fringe 

 behind of the same colour. Scutellum bidentate. Abdomen finely
