Antennae rather long, basal segment extended beyond apex of head for 

 less than half its length, second segment one third longer than third, fourth 

 segment only a little shorter than second. Head nearly nude, postocular and 

 anteocular space to apex of antenniferous tubercles nearly equal. Pronotum 

 deeply constricted just behind middle, very sparsely setose, anterior lobe rather 

 globose, a little wider than long, shorter posterior lobe sparsely punctate, 

 sordid yellow, more or less infuscated. The hind femora have a preapical 

 brownish band. The fore tibia are straight and unarmed in the male. The 

 fore femora are armed with two series of spines towards apex at least, the 

 inner series consists of three stronger spines beyond the middle between which 

 are several smaller spines, the outer series near apex consists of two or three 

 minute teeth. 



Length 6 mm.

Ligyrocoris (Neoligyrocoris) coloradensis new species. 



Very closely related to uitidulus Uhl. and only distinguishable from that 

 species by comparative differences. Coloration and pattern of markings much 

 the same. Head longer, plainly longer than wide, sides of antenniferous tuber- 

 cles nearly as long as eye ; first segment of antenna longer, apex of tylus not 

 reaching the middle point of it. Pronotum with anterior lobe more swollen 

 and over twice as long as posterior one : seen from the side the former is 

 more elevated; collar wider; dorsal surface more densely pilose. Armature 

 of fore femora and character of the tibia much the same as in nitidulus. 

 Transverse fascia of corium not so conspicuous, inwardly and posteriorly fused 

 with apical spot, leaving a small inconspicuous pale spot outwardly. Mem- 

 brane reaching apex of abdomen generally entirely pale or faintly embrowned 

 within. Length 6^-7 mm. 



Described from five (^(^ and four JJ collected in northern Colorado April 

 II, 1898, by E. D. Ball. Type and paratype my collection, 6 paratypes in 

 Coll. Prof. E. D. Ball and i paratype in Coll. of Prof. Herbert Osborn. 



It is very likely that Van Duzee's record of nitidulus from Colo- 

 rado should be placed here. 



Ligyrocoris (Neoligyrocoris) nitidulus L'hler. 



Uhler. No. Amer. Fauna. VH, 262, 1893 (Pamera). 

 Banks. Cat. Hem. 64, 1910 (Ligyrocoris). 



In his Check List and various papers Uhler recognized the genus 

 Ligyrocoris and it therefore seems strange that he failed to recognize
