The head as seen dorsally and laterally is very much the same as 

 in nitidicollis but the post-ocular space is, if anything, a little longer 

 than the ante-ocular space to apex of antenniferous tubercles. The 

 fore femora are profusely long setose and provided for three fourths 

 their length with numerous strong teeth set in two irregular series, 

 at least apically. 



Distribution. — Texas (Stal) ; Guatemala (Dist.) ; Huachuca Mts., 

 Ariz, (my coll.); "Ariz.," "Tex.," San Diego, Tex., Palm Springs, 

 Calif. (U. S. N. M.), San Diego Co., Calif. (Van Duzee). 



Ligyrocoris delitus Distant. 



Distant. Biol. Cent.-Amer. Het., I, 201, Tab. XVIII, fig. 20, 1882. 



This is a small species about 4 mm. long, of which Distant gives 

 a very good description and figure. It is closely related to litigiosus 

 and Distant remarks it is allied to baltcatits but this latter species 1 

 have not been able to recognize. Considerable variation occurs in 

 the color and extent of markings. The head and anterior lobe of 

 pronotum and scutellum varying to pale ferrugineous. The post- 

 median transverse fuscous fascia of the corium is frequently not ex- 

 tended to the margin but confined to the inner area. The head and 

 pronotum are quite pilose. The fore femora are armed with three 

 small preapical teeth.
