HEMIPTERA OF LOWER CALIFORNIA. 269- 



Malthacus n. sp.? 



A pair of these insects are in the collection labeled 

 '' Cal. 2," but they are too much altered to bear descrip- 

 tion. 



Oncotylus guttulatus n. sp. 



Pale whitish or yellowish-green, robust, form of a stout 

 LygHs; the upper surface distinctly pubescent, minutely 

 flecked with black, which is finer and closer on the cori- 

 um, but forms remote round dots on the head, pronotum, 

 legs and antennas. Head small, pale green, the vertex 

 and front conformly convex, the tylus continuing the 

 curve, tapering toward the tip; the basal joint of antennce 

 short, second joint rod-shaped, about as long as the inner 

 margin of the clavus; rostrum reaching upon the middle 

 coxae, pale testaceous, piceous at tip. Pronotum strong- 

 ly convex, moderately polished, a little wider than long, 

 not obviously punctate, a little wrinkled next the humeri, 

 the callosities very large, tumidly convex, transverse, the 

 middle line obsoletely carinated with an indent at the front 

 of the line on the margin, the humeri broadly rounded; 

 the lateral margins almost directly oblique, sharp-edged. 

 Scutellum moderately convex. Hemielytra remotely, 

 finely and obsoletely punctate, the costal margin very 

 feebly curv^ed, with the veins prominent, and the area a 

 little deflexed; the membrane whitish, clouded unevenly 

 with fuliginous behind the middle and towards the tip. 

 Tibiee pale yellowish with numerous streaks and a few 

 dots black. 



Length to tip of venter, 4^-43/^ mm. Width of pro- 

 notum, 2 mm. 



Several specimens, all more or less damaged, are in 

 the collection. They were collected at San Julio in 

 April, and El Rosario in May, by Mr. Charles D. Haines. 

 There is much difference in the amount of spotting upon, 

 the hemielytra and pronotum.
