that on the tarsi beneath golden yellow ; the apical joints of the 

 tarsi pale ferruginous. Abdomen ovate, very closely and finely 

 punctured • the apical margins of the segments have pale f asciae, 

 sometimes white, the first usually interrupted ; the sides of the anal 

 rima slightly fulvous. B.M. 



Male. Length 3-3| lines.— Brassy green, very closely and finely 

 punctured, the apex of the clypeus, the labrum, and mandibles 

 yellow, the latter ferruginous at their apex ; the antennae longer 

 than the thorax, fulvous beneath and fuscous above, the scape 

 black ; the thorax has a central impressed line and a short one 

 over the tegulae ; the tegulae yellow ; the legs sulphur-yellow, the 

 coxae and trochanters black or rufo-piceous, the anterior coxae 

 yellow beneath ; the tibiae and femora have some rufous stains ; 

 the wings hyaline and iridescent, the nervures testaceous. Abdo- 

 men elongate, shining and subclavate, the apex obtusely rounded ; 

 the margins of the segments depressed, and having a thinly scat- 

 tered griseous pubescence, particularly on the sides. B.M. 



I have carefully reexamined the type of A. tumulorum, having 

 cleaned the specimen ; and I find the head and thorax are metallic, 

 the mandibles, clypeus, and labrum yellow ; the antennae pale ful- 

 vous beneath, with two or three of the apical joints entirely fuscous, 

 and in other respects agreeing with our insect. Kirby describes the 

 wings as "Alae fuscescentes ;" this arises from the insect being 

 gummed on card and the four wings placed over each other : there 

 are two specimens on the card ; in one the brassy colour is now ap- 

 parent. The species is found in all parts of the United Kingdom, 

 and very abundant in Lundy Island, in the Bristol Channel.

Female. Length 4 lines. — Head and thorax brassy green, finely 

 and closely punctured ; the clypeus with a bright violet tint ; the 

 flagellum pale fulvous beneath. Thorax, the articulations of the 

 legs and the apical joints of the tarsi pale testaceous ; the wings 

 hyaline and iridescent, the nervures pale testaceous. Abdomen 

 obscure nigro-aeneous, very finely and closely punctured and shining ; 

 the apical margins of the segments with white pubescent fasciae ; 

 the sides of the apical rima slightly fulvous. This species is very 

 distinct from H. gramineus. 



The insect described closely resembles the female of If. tumulorum ; 

 it appears possible that it may be a variety of that insect. It was 

 taken at Deal in August some years ago.
