Head nilidulous, not narrowed behind the eyes, witli tlie jjalpi and 

 mandibles ferrugineoiis. Antennae entirely testaceous. Metathorax with 

 five upper areae, of which the central is hardly impressed. Abdomen 

 compressed and centrally ferrugineoiis ; basal segment slender and straight, 

 with the post-petiole gradually explanate a[)ically ; second segment longer 

 than broad. Legs testaceous, with the hind coxae basally and sometimes 

 their femora infuscate. Wings narrow and hardly clouded, with the tegulae 

 testaceous. Length, 4-7 mm. 



Ireland, rare (Haliday). I took a specimen, which I believe to be 

 referable to this species, by general sweeping in a marshy spot at Barton 

 Mills in Suffolk, on nth June, 1900.

Shining, punctulate, black. Head with mandibles centrally broadly red 

 and the eyes glabrous. Antennae filiform, half the length of the body, 

 with the flagellum basally red beneath. Metathorax caudately produced 

 behind the hind coxae ; central area broad, strongly excavate and nitidu- 

 lous ; upper lateral areae very incomplete. Abdomen longer than head 

 and thorax, of ? strongly compressed and lanceolate ; immaculate or with 

 the second and third segments partly badious ; basal segment flat and 

 quite straight with the petiole slender, linear and a little longer than the 

 post-petiole, which is gradually dilated apically, more than twice broader 

 than the petiole and in $ laterally immarginate ; second segment with no 

 lateral impressed lines. Legs very variable in colour, usually red with the 

 anterior coxae, trochanters and base of the intermediate femora, black ; 

 hind legs black with the tibiae red and tarsi infuscate ; calcaria short and 

 curved. Wings slightly clouded with the areolet entire ; radix and tegulae 

 testaceous or stramineous, the latter often infuscate. Length, 3 -S mm. 



The legs are sometimes mainly infuscate or piceous, at others nearly 

 entirely testaceous. Haliday says the legs of A. cultellator are red, with 

 only the posterior coxae black, and that its abdomen is hardly shorter than 

 the hind legs and centrally piceous-red. 



This species may be distinguished by its much longer and more strongly 

 compressed abdomen (recalling that oi C/ine/ion anccps, Curl.), nmch more 

 slender petiole, smaller head and slightly shorter tibiae. 



Holy wood (Haliday). It is probably uncommon in Britain, since the 

 only example I have seen is a female given me by Mr. ^^'. I L Turk, who 

 captured it at Aldeburgh in Suffolk, in September, 1899.
