Insects. 1153 



punctured, conical, not depressed above; a lateral macula on the mar- 

 gin of the first segment, the three following with a continuous margi- 

 nal fascia of reddish yellow hair ; the margins beneath have a similar 

 fascia. The fasciae above are sometimes interrupted, and in long-dis- 

 closed specimens the pubescence is nearly white. 



Male. — Length, 6 — 7 lines. Black. The face and sides of the 

 thorax clothed with a reddish yellow pubescence, which also thinly 

 clothes the coxae and femora ; the anterior coxae are dentate. Scu- 

 tellum bidentate. The abdomen convex, an angular macula at the 

 lateral margins of the first segment, and the three following have a 

 marginal fascia of reddish yellow pubescence ; a minute tooth at the 

 extreme lateral margins of the fifth segment, a larger tooth at the base 

 of the sixth, with two stout ones at the apex, bidentate at their tips. 



This species very closely resembles C. conica, but it is much larger, 

 and the abdomen is convex above and beneath, whereas in C. conica 

 it is more or less depressed above. I observed this species entering 

 the burrows of Anthophora retusa this season, in August. 



Sp. 4. Ccelioxys umbrina, Smith. 



Male. — Length, 4f lines. Dark brown. Face covered with longish 

 pale fulvous hair : the cheeks and anterior tibiae clothed with white 

 pubescence ; the anterior coxae bidentate. The disk of the thorax is 

 fulvous and the sides paler. Scutellum bidentate. Abdomen ; the 

 base considerably attenuated, the first segment has a fringe of pale 

 brown hair, the four following have a continuous fascia of the same 

 colour, the sixth segment has an acute tooth at its base laterally, and 

 the two stout ones which arm the apex are bidentate at their tips. 



I captured the insect here described about six years ago, in Hamp- 

 shire, and have not yet succeeded in meeting with more specimens. 

 I have taken a female Ccelioxys at the same spot, which probably is 

 the same species. It differs from C. conica in having the margins of 

 the abdominal segments much depressed, and its scutellum is not den- 

 tate ; these are strong characters, but I have pointed out the particu- 

 lars in which it differs from C. conica, and hope to satisfy myself by 

 further observation if it be the female of umbrina or not. I do not 

 feel inclined to raise it to a distinct species. The male I bred from 

 the cocoons of Saropoda bimaculata.
