width; viewed from the side it is produced beyond the eye for about 

 the length of the eye; facial angle less than a right angle. Vertex 

 opaque, obliquely striate, with a longitudinal sulcus, distinct at base; 

 base of the vertex slenderly carinate and a little angled at the 

 middle. Clypeus distinctly prominent, strongly distinguished from 

 the front; jugse convex, almost tumid; loras convex, distinguished by 

 a slight suture below the antennae ; gula short, oblique. First an- 

 tennal joint surpassing the clypeus by one-half its length; second 

 scarcely thinner at apex; third and fourth together about two-thirds 

 the length of the second and distinctly thinner, but scarcely seta- 

 ceous. Pronotum distinctly transverse, moderately sloping; hind 

 margin feebly sinuated; sides straight with a smooth carina; anterior 

 with a slender smooth collar; callosities prominent, contiguous, 

 nearly attaining the anterior margin, posteriorly with an angular 

 emargination between them. Basal lobe of the scutellum a little 

 exposed. Elytra surpassing the abdomen, parallel or nearly so; 

 cuneus long, nearly horizontal; fracture small; smaller areole of 

 the membrane unusually large. Prosternal xyphus conspicuously 

 margined. Rostrum long, reaching the apex of the second ventral 

 segment. Hind tarsi long, second joint on its lower margin dis- 

 tinctly shorter than the first. Arolia small, widely divergent. 



This genus differs from Lygidea by the longer first joint of the 

 hind tarsi, the more produced and subhorizontal head, opaque ver- 

 tex with an angled basal carina, longer basal joint of the antennae, 

 longer rostrum, more slender pronotal collar and the more irregular 

 and distinct pronotal puncturation. It is nearer Camptochilella, 

 but the much longer and more horizontal head, the more opaque 

 vertex, the more distinct incisure between the clypeus and vertex, 

 the longer rostrum, the approximate callosities and the longer first 

 joint of the hind tarsi will distinguish It. 



Type: Lygidea ruhecula var. hirida Reut., 1909 (founded on 

 Reuter's unique type specimen now in my collection). 



Diplozona n. gen. 

 Closely allied to Cimatlan Dist. Body small, polished; coarsely 

 punctured; antennae Incrassate.
