THE CANADIAN ENTOMOLOGIST. 51 



Described from fourteen specimens from Rifle, Ridgway and Dolores, 

 Colo. This and the two preceding species belong to a small group 

 which includes jucunda, Uhler ; costamaculata, Van D., and modesta, 

 O. & B. They possess the second cross nervure, and have been 

 referred to Allygus by some authors. 



Athysanus litigiosus, n. sp. 



Broad and short, vertex almost parallel margined. Colour pale, 

 with three transverse bands on vertex and dense irrorations on pronotum 

 and elytra fuscous. Length, 5 mm.; width, nearly 2 mm. 



Vertex broad and short, scarcely extending in front of the eyes, two 

 and one-half times wider than long, scarcely longer on middle than against 

 eye. Front very broad above, narrow below, scarcely longer than wide, 

 disc feebly convex. Pronotum broadest behind, where it equals or 

 slightly exceeds the width of the eyes, nearly three times the length of the 

 vertex. Elytra broad, venation strong, resembling extrusus, the central 

 anteapical cell rather long, enlarged at the apex. 



Colour: anterior half of vertex black, almost divided into two 

 transverse bands by a light line which is parallel with the yellow line 

 separating the vertex and front, posterior half of vertex orange yellow, 

 divided by an interrupted transverse fuscous band. Pronotum ivory 

 white, heavily irrorate and vermiculate with fuscous, a few definite spots 

 behind the eyes. Scutullem dark testaceous, the margins and a pair of 

 irregular longitudinal lines white. Elytra ivory white, the nervures and 

 many irregular reticulations fuscous, a band on tip and another across the 

 apex of the clavus, a spot on the costa between the bands and another in 

 the inner discoid cell fuscous. Between these bands subhyaline, 

 especially along the margin. Face all black except a light line just below 

 and parallel with the basal line. Legs black, the spines and an annulus 

 on the posterior tarsus orange. 



Genitalia : male valve broad and obtuse, angular, plates broad at 

 base, about twice the length of the ultimate segment, roundingly 

 narrowing to the acute apices, from which extend a pair of short 

 divergent filaments. 



Described from a single male received from Mexico (O. W. B.) ; 

 probably from Cuernavaca. It is very distinct from any described form, 

 and is not a typical Athysanus. The head and markings suggest 

 Scaphoideus, but the form is too broad. The elytra are very much like 

 some Phlepsius forms.
