Type: No. 13229, U. S. National Museum. 



This peculiar species can be distinguished from all other 

 species of Leptoglossus known at the present time by the stout 

 spine conspicuously projecting from the tip of the head. Its 

 geographical distribution extends from Colorado west to the 

 Pacific Slope. The species may become of economic import- 

 ance, as it is already recorded to be injurious to plum trees and 

 almonds, puncturing the young fruit. 



Leptogossus occidentalis, new species. 



Body oblong, reddish brown, densely pubescent; head nearly as long 

 as the thorax, with two black longitudinal stripes above, the outer 

 one continuing along the exterior part of basal antennal joint, also a 

 short, blackish streak at the gula; tylus rounded in front, a little 

 knobbed at tip; rostrum reaching to the third and fourth abdominal 

 segment; antenna? usually pale brown; the terminal joint darker 

 and stout, nearly equal in length to the third joint; the second longer 

 than the first. Thorax less depressed towards front, deeply punctured 

 and irregularly wrinkled; lateral margins near the middle sinuated, 

 the humeral angles broadly rounded and a little reflexed, a transverse 

 sunken line before and behind the callosities; disk more or less convexly 

 rounded and with a few scattered black dots. Scutellum blackish at 

 base, tip pale, and a transverse depression on the middle. Hemilytra 

 with a medium pale zig-zag line across the corium, formed by the 

 color of the nerves, sometimes nearly indistinct; before and behind this 

 pale line the surface is of a darker brown, appearing somewhat velvety 

 in fresh specimens; the membrane dark bronze. Abdomen dorsally 

 orange with transverse black patches; connexivum sometimes narrowly 

 edged black and the base of incisures yellowish. Underside of body pale 

 reddish brown, sprinkled with large and smaller black spots and a shallow 

 impression dawn the ventral part. Legs pilose, pale reddish brown, 

 the spines of the femures black only at the tip; upper side of femora 

 blackish streaked with pale interruptions ; membranous expansion of the 

 hind tibiae shaped as in the preceding species, but less broadened; the 

 inner and outer sides of expansion equally wide, reddish brown, with an 

 irregular transparent spot in the middle and dotted black before and 

 at the apex; the expanded inner side armed with a few small double 

 spines, while the outer side has only two single minute ones. 



Length 16 to 18 mm. ; width across thorax 4 to (> mm.
