Tylocentrus reticulatus n. sp. PI. 2, figs. 39, 40. 



Broad oval, tapering posteriorly. Face flat, about twice 

 broader than long, the occipital and basal margins behind the 

 ocelli a little elevated; surface closely and evenly punctured; 

 anterior edge of the cheeks feebly arcuated; clypeus produced 

 beyond the line of the cheeks about as far as the distance be- 

 tween the ocelli. Pronotum closely and evenly punctured, with 

 a distinct but not strong median carina; anterior margin of the 

 metopidium prominent, the surface above each eye with a large 

 callous; suprahumerals viewed from before horizontal or nearly 

 so, reaching the line of the humeral angles ; exposed sides of 

 the scutellum filling in the sinus of the posterior pronotal pro- 

 cess. Tibiae flattened but not at all foliaceous. 



Color variable, usually, fulvotestaceous shading to ferrugin- 

 ous on the face and anterior margin of the pronotum ; Supra- 

 humerals, a lozenge shaped mark on the rounded disk of the 

 pronotum, tip of its posterior process and disk of the exposed 

 portion of the scutellum ferruginous in pale examples, fuscous 

 or black in dark examples. Sides of the face and callosities 

 sometimes blackish; anterior margin of the cheeks, clypeus and 

 apical angles of the scutellum pale. Basal one third of the 

 elytra testaceous shading to ferruginous or blackish at base; 

 apical two thirds whitish hyaline with the nervures and a costal 

 cloud next the pale basal portion ferruginous or fuscous. Be- 

 neath pale, more or less white-pruinose; femora, three bands on 

 the tibiae and the pygofers of the female ferruginous or black- 

 ish. The male is more strongly colored with the ferruginous 

 marks mostly black; the face black with the anterior margins 

 and median line pale ; the coriaceous portion of the elytra paler 

 posteriorly imparting the appearance of a transverse band. 

 Length 4-5^ mm. 



Described from one male in the Cornell University collec- 

 tion and five females taken at St. George and Leeds, Utah, in 

 July, by Prof. Wickham The male from Arizona is much 

 smaller and wants the suprahumeral spines, and may represent 

 a distinct species although I consider this altogether unlikely. 

 The Arizona male bears the MS name TylopJiorus ramosus 

 Uhler and in case it should prove to be distinct the name here 

 applied by me should follow the female.
