74 LOPHYRUS V1RKNS. 



SECTION 1. Accessory nervure in hind wings received 

 a little beyond the middle. Head and thorax strongly 

 punctured. 



A. Inner spur on the posterior tibise dilated into a leaf-like 

 expansion. A more or less clearly-defined fascia across 

 the vertex. Antenna 23-jointed (species 1 and 2). 



1 (2) A broad black fascia on the front ; breast broadly black ; 



scutellum slightly punctured. Virens. 



2 (1) No fascia on vertex or black on breast; scutellum strongly 



punctured. Dorsatus.

Lophyrus virens, Klug, Berl. Mag., vi, 58, 7; Fall., Mon., 16, 

 7; Dbm., Prod., 91, 28; Htg., Blattw., 

 119, 2, pi. xi, f. 6 (lar.) ; Thorns., Hym. 

 Sc., 1,^54, 2 ; Voll., Tijd. Ent., xvi, 1, pi. i ; 

 Andre, Species, i, 61 and 65 ; Oat., 8,* 2 ; 

 Cam., Fauna, i, 47, 1. 



Testaceous, shortly pilose, mesonotum covered with scattered, mode- 

 rately large punctures. The greater part of the scape, a transverse 

 mark over the antenna, a quadrate spot on middle lobe of mesonotum, 

 a longer narrower one on each of the lateral lobes, two or three small 

 marks in front of the scutellum, the extreme apex of scutellum, most 

 of the metanotum, a mark on mesopleura, the greater part of the 

 breast, and a broad transverse line on each of the abdominal segments, 

 black. The extreme base of posterior coxae is also black, and the apex 

 of hind tibise; the tarsal joints at the apex are fuscous. Wings 

 hyaline, nervures pallid testaceous. 



$ black, densely covered with a pale pubescence; pronotum, a 

 roundish mark on mesopleura, and legs, testaceous ; the sides and 

 ventral surface of abdomen red. 



Length 3 4 lines. 



Most of the Continental specimens of virens I have 

 are darker (having much more black on the thorax) 

 than the Scotch examples I have described. In most 

 Continental specimens the pleurae are black, save a tri- 

 angular testaceous mark ; and the lobes of the meso- 

 notum are black, only testaceous at the edges. The 

 black stripes on the dorsum of abdomen tend to become 

 confluent as in dorsatus.
