be expected. Differs from A. -piccus in the form of the 

 thorax and the scarcely pubescent surface. 

 Occurs in Arizona near Fort Yuma. 



Lacon ileimis n. sp. 



Brown or ferru^^inous, subopaque, sparsely clothed with 

 yellowish, scale-like hairs, antenna? and legs paler. Head 

 coarsely and closely punctate. Thorax a little longer than 

 wide, sides arcuate in front, from middle to base nearly 

 straight, margin crenulate, hind angles slightly prom- 

 inent externally, without carina, disc coarsely, closely 

 punctate, a depression in front of the scutellum. Elytra 

 not distinctly striate, the intervals faintly indicated, punc- 

 tures coarse, closely placed and in feebly indicated rows 

 with closely placed and but little liner punctures in the 

 intervals. Body beneath with coarsely, closely and equal- 

 ly disposed punctures. Propleuras without groove for the 

 tarsus. Length, .28-. 32 inch; 7-8 mm. 



By all its structural characters this species should take 

 its place near Lczclciicii ?i^ given by Candeze, but differs 

 from that by its smaller size and the elytral sculpture. 

 The elytral punctures are so closely placed that it is dith- 

 cult to distinguish those of the stride. 



Occurs at Tucson (Wickham) and near Yuma, Ariz. 



Chrysobothris bicolor n. sp. 



Form of texaiia, but without trace of costa^ or fovea? 

 on the elytra, head and thorax bronze black, elytra green 

 feebly shining. Clvpeal emargination broadly oval. Head 

 closely punctate, vertex more finely, sparsely pubescent. 

 Thorax rather more than twice as wide as long, sides 

 slightly divergent posteriorly, hind angles slightly co- 

 arctate, anterior angles obliquely truncate, disc regularly 

 convex without depressions, coarsely punctured, less 

 closely at middle, densely at the sides. Elytra slightly
