GO ^Ii'. C. 0. WuterliOLise on Coleojjtera 



fascia extending from the suture to the niarg-in. At the 

 apex a small lunate sj)Ot. At the niaririn there are six 

 or seven acute teeth, with the usual acute apical spines. 

 Prosternura horizontal, shining, moderately closely and dis- 

 tinctly {)unctured, very slightly produced at the apex, which 

 is transversely rugnlose. 



Long. 17, lat. 7 mm. 



Jlab. N. Argentina {Mrs. Leach). 



This very beautiful little species may be placed near 

 C. riiiiior, but its markings somewhat resemble those of 

 coDipta. 



Conognaiha ornata, sp. n. 



Closely resembles G. leachi, and at first I believed it to be 

 the same, but it differs in the following points : — Thorax 

 slightly but distinctly widened just before the posterior 

 angles, the impressions deeper and much more strongly 

 })unctured than the rest of the surface. Prosternum not 

 ])roduced in front, but sloping down. The elytra are rather 

 darker green, the markings brownish yellow, but very 

 similar. The stripe is not narrowed behind and after turning 

 to the margin it is not joined to the narrow yellow on the 

 marginal costa, which appears only as a stripe below the 

 shoulder. The apical spot is larger. 



Long. 17, lat. 7 mm. 



IJah. La Plata, Salta (ex coll. Fry). 



Conognatha ahdominalls, sp. n. 



Elongate, parallel, deep steel-blue, the elytra with a 

 pnrple tint, abdomen entirely dull reddish yellow. Clypeus 

 and antennse with a slight green shade. Tliorax strongly 

 convex, very finely punctured, obliquely narrowed in front, 

 the sides nearly straight, not quite so broad as the elytra at 

 the posterior angles, which are very acute, convex, without 

 any impression. Scutellum elongate, slightly narrowed to- 

 wards the apex, which is acute. Elytra parallel, a trifle 

 wider just before the apex than in the middle, with numerous 

 costee, those near the suture strongest but not extending 

 to the base ; apex obtusely rounded, with numerous 

 acute teeth, the sutural one and the one next to it more 

 prominent than the others with an emargination between 

 them. Prosternum very convex, finely but very distinctly 

 ])unctured, obtu>!e in front and scarcely produced. Abdomen 

 ilull reddit>h yellow, with slight purple reflections, nearly 

 straight at the apex. $ .
