men lying parallel to its own ; in this way it flew about a 

 northern bunk, alighting occasionally upon the grass that 

 covered it, when at last it found its retreat, at the mouth of 



which it stopped, and entering it backward, drew in the victim 

 in spite of its struggling, with the greatest facility. 

 The following species are recorded as British. 



1. sabulosus Fab. ? .— ruficornis Panz. 77. 17-9 .— petiolatus 



Paiiz. 46. 12. ? var. 



Expanse 9 lines. Black, antennjB and legs ferruginous, 2 basal joints of 

 the former black above ; base of thighs, excepting hinder pair, black ; in- 

 ternal margin of eyes and 4 dots on the clypeus ferruginous; an inter- 

 rupted line on the collar, a spot on the scutel, one under each wing, 4 on 

 the body and a band near the apex, yellow. 

 I took a female of this, and a male of the following, several 



years since in Suffolk ; and Capt. Blomer met with it, I believe, 



in the Isle of Man. 



2. fulvicornis Fab.— Curt. B. E. 580. $—Panz. 98. 18. c?.— 

 frontalis Panz. 4'6. 1 1. c?? I consider these to be the males of 

 the foregoing species, for the specimen I have figured agrees 

 with Fabricius's description, although Panzer's plate does 

 not, but this figure is evidently inaccurate, the antennae hav- 

 ing J 8 joints. 



Black, shining, minutely and thickly punctured, hoary-pubescent; an- 

 tennae and legs ferruginous, basal joint of the former black above, yellow 

 beneath, 2nd black, a few of the following dusky above, thighs black at the 

 base, inner margin of eyes and clypeus, a spot at the base of the mandibles, 

 an interrupted line on the collar, a spot on the scutel, one beneath each 

 wing, 2 on the 3rd segment of the abdomen and a band at the base of the 

 6th, yellow ; tips of the 4 anterior thighs beneath of the same colour, and 

 there is a minute spot on each side the 2nd joint. 



3. arvensis L/;«?i. — clavata Z)<?G. — U-flavum Paw2:. 1 7. 20. ? . — 

 bipunctatus Fab. var. 



Male (Ji to 9 lines expanse. Black, antennee rufous beneath, basal joint 

 yellow ; palpi, margins of eyes and clypeus and outside of mandibles yel- 

 low ; a line on the collar, a spot on the scutel, 2 beneath each wing, a spot 

 on each side the 2nd and 4th abdominal segments, a band on the 3rd and 

 a narrow one on the 6th, yellow : legs ferruginous, yellow inside, base of 

 thighs and a stripe on the inside of the 4 anterior tibiae black. Ohs. some- 

 times the coxae and 3rd segment of the abdomen are spotted with yellow 

 beneatli, and the 2 yellow basal spots above are wanting. Female 1 2 lines : 

 similar to the male, excepting the abdomen ; on the nodule of the peduncle 

 are 3 yellow dots, the 2nd, 3rd, and 5th segments are yellow, edges of the 2 

 former black, and there is a large yellow spot on each side the4th. Obs. some- 

 times there are only 2 dots on the peduncle or none, and occasionally the 3 

 spots on the 4th segment form a band ; in others the face, except the inner 

 margin of the eyes, and the antennae, except the basal joint, are black. 

 The females are common on all sandy banks in August and 

 September, and the males on the Fern. 



4. pratensis Jurine^ jd. 10. G. 19. ? . 



Lengtli 7 lines. Black, inner margin of eyes and clypeus, basal joint 

 of antenna>, base of mandibles, a line on the collar, a spot on the scutel, 

 2ii(l and 3rd segments of abdomen, and a band at the base of the 5th ? yel- 

 low, coxnc trociianters and base of anterior thighs black. 



I have never seen a British specimen. 



Tlic Plant is Selimim palustrc {Msirah Milk-weed).
