Insects. 1151 



letes Daviesana of Kirby's MSS. I have found it in the nests of that 

 insect in Hampshire, and in several localities in Kent, viz., Bexley- 

 heath, Darent-wood, Charlton and Erith ; also at Weybridge in Sur- 

 rey. It appears early in July, and, for a bee, is remarkably indolent. 

 The males are fond of taking their repose in a species of Leontodon, 

 where they appear to enjoy themselves in a state of luxurious intoxi- 

 cation. The females are not quite so inactive as the males, but both 

 sexes may easily be taken with the fingers. 



Genus. — Ccelioxys, Latreille, St. Fargeau. 

 Anthophora, Fab. Anthidium, Panzer. Apis, Linn., Oliv., Kirby. 



Two submarginal cells. Maxillary palpi three-jointed. 



Sp. 1. Ccelioxys qtjadridentata. 



Female. — Length, 4 — 5j lines. Black, coarsely and closely punc- 

 tured on the head and thorax. The face below the antennas clothed 

 with a pale yellow pubescence, which is very short and fine on the 

 clypeus. Disk of the thorax naked, the sides and beneath clothed 

 with a pale yellow pubescence. The scutellum bidentate. The an- 

 terior femora are fringed behind with pale hairs, the calcaria rufous. 

 Abdomen conical, depressed above, with deep scattered punctures, a 

 thin lateral fringe of pale hair at the base, there is also an angular 

 patch of white hair on each side of the basal segment, the rest of the 

 segments have a fringe of the same colour on their margins, sometimes 

 the first and second interrupted. 



Male. — Length, 3^ — 5 lines. Black. Head and thorax coarsely 

 and closely punctured. The face clothed with bright yellow hair. 

 The sides of the thorax clothed with a pale yellow pubescence, be- 

 neath with hoary pubescence. The anterior legs have a fringe of the 

 same colour on their femora, and their coxae are armed with an obtuse 

 spine. The abdomen has a thin pale fringe on each side at the base, 

 and also an angular patch of white, the second, third and fourth seg- 

 ments have a continuous marginal fascia of white, sometimes inter- 

 rupted, the fifth segment has a minute tooth at its extreme lateral 

 margins, the sixth is quadridentate, the lateral teeth are small and 

 acute, the inner pair stout and bidentate at their apex. 



The yellow pubescence turns to white in long-disclosed specimens, 

 and the marginal fasciae are nearly obliterated. 



The male is the Apis quadridentata of Linnaeus ; his own specimen 

 is still preserved in the Linnean cabinet.
