240. Trichius costipennis. 



(inoiimus costipennis, Janson, JS'oles Leydcn Mus. xii, 1890, p. 128. 

 Gnorinnis viridis, Jordan, Novit. Zoolog. 1894, pp. 486, C92, pi. 13, 

 lig.3. 



Deep metallic greeu, thickly clothed beneath, except at the 

 middle of the abdomen, \vith a short greyish-yellow pubescence, 

 which also forms a narrow line at each side of the pronotum 

 (continued a little round the posterior angles) and three small 

 patches at the base of the pygidium. 



It is a very large species and rather stoutly built and convex. 

 The head is densely and rugosely punctured and, together with the 

 pronotum and the external margins of the elytra, bears very 

 minute setae. Tl\\eclypeus is about as long as it is broad and deeply 

 incised in front. The pronotuin is strongly punctured, about as 

 long as it is broad, much narrowed in front but scarcely at all 

 behind, with all the angles sharp, the front ones acute and the 

 posterior ones right angles, the sides sinuated and the base gently 

 curved. The scxdellum is broad and bears a few punctures. The 

 elytra are deeply sulcate, the sulci being rugose at the bottom, and 

 the lateral and apical margins are finely rugose. The p>/g'uUum 

 is rather feebly rugulose. The mesostenmm forms a short com- 

 pressed vertical lamina between the middle coxae. The club of 

 the anienna is short in both sexes and the leys are modei-ately, 

 but not extremely, slender. 



S . The front tibia is simple, armed only with a blunt apical 

 prolongation, and the abdomen is channelled along the middle, with 

 a median line of pubescence. 



$ . The front tibia is feebly bidentate, the abdomen is convex 

 and bare along the middle, and the pygidium has a slight depression 

 at the apex, which is coarsely granulated. 



Lenf/ih 21-24 mm.; hreaJth 11-12 mm,
