pulvilli ; tibiae shortly and closely setulose ; calcaria strongly curved and 

 almost shorter than the onychium. ^\'ings distinctly clouded ; stigma 

 infuscate, radix and tegulae stramineous, latter sometimes dark ; areolet 

 entire. Length, 4-6 mm. 



This species is very similar to A. ves/a/is, excepting the structure of 

 the basal segment and the coloration of the legs ; the tarsal claws are 

 less elongate than those of A. bicolor. 



Lakenham, Norfolk, in May (Bridgman) ; liickleigh, in the middle of 

 September (Bignell) ; common at Shere (Capron) ; Chobham, in July 

 (Beaumont); Greenings in Surrey (\V. Saunders); Tostock in Suffolk 

 (Tuck). It is probably quite a common species. I have taken it at 

 I>yndhurst, and in a dead rabbit at lirandon in Suffolk, in June. Dr. '!'. 

 R. Cassal has given me a female bred early in May, 1900, at Ashby near 

 Doncaster, in a cage containing larvae o{ Acidalia inar^inepiinctata^ Goze.

This species, as far as one is enabled to judge from the very short 

 description, is closely allied to A. bicolor in the coloration of the abdomen 

 and legs, but it is very different in its distinctly punctate head and thorax, 

 and in having only the base of the abdomen black. All the tibiae, 

 excepting the apices of the hind pair, and the anterior femora are testa- 

 ceous. Length, 7 mm. 



It was originally recorded from Ireland by Haliday, and no one has 

 ventured to subsequently identify it but Bignell, who somewhat boldly 

 records it from Bickleigh in Devon, on 3rd August, upon Bridgman's 

 authority. I have examined the latter specimen, which is a female, and 

 find hardly any distinction between it and those of .^. exilis \ the onyches 

 are stout and calcaria longer than the onychium.

 all narrowed behind the eyes ; cheeks strongly tumidous, the space between 

 the eyes and the mandibles broad ; palpi and centre of mandibles tes- 

 taceous. Antennae stout, rather shorter than half the body, filiform with

 neath. Thorax a little narrower than the head ; notauli anteriorly distinct ; 

 metathorax short, nearly twice higher than long ; central area broad and 

 only slightly impressed, apophyses not strong. Scutellum elevated. Ab- 

 domen of $ fusiform, apically sub-compressed and as broad as the thorax ; 

 black with the sub-quadrate second and third segments, together with the 

 gradually dilated apex of the first, entirely red, the following conical and 

 gradually contracted towards the ajiex ; basal segment distinctly curved 

 and nearly as long as the hind coxae and trochanters ; tercbra not exserted.
