Vol.1] Van Diizee. — Lake Tahoe Hemiptera 247 



Color of head, pronotum and mesonotum fulvo-testaeeous, becoming 

 more brown on mesonotum, where the dark irrorations are more con- 

 spicuous. Pronotum darkened either side of the median carina, with 

 about four brown points beliind each eye; vertex sometimes showing- 

 dark irrorations. Elytra testaceous-gray with a tinge of brown and 

 marked with two obscure transverse brown bands, one, more distinct, at 

 the basal third, the other at the apex of the clavus, the costa with a 

 narrow fuscous line; all the nervures, including the costal, pale, slenderly 

 edged with fuscous and broken by numerous white transverse veinlets. 

 Wings fuscous at apex with darker nervures. Front and clypeus whitish- 

 testaceous, immaculate or nearly so. Pectus and legs brown, inferior 

 aspect of pronotum testaceous, knees, tips of the tibiae and tarsi pale. 

 Abdomen black, white-pruinose, the slender edges of segments and genital 

 pieces pale. Antennae brown, the setae black. 



Described from numerous examples taken June 20 to the last 

 of July from the level of Lake Tahoe up to 8000 feet. This 

 species seems to live entirely on the lodge-pole pine, although it 

 was occasionally captured on other trees whence it had evidently 

 flown from the pines. 



Catonia succinea, new species 



Form and aspect of majusculus ; a little smaller and nearly immacu- 

 late but closely allied to it in most of its characters; pale amber-brown 

 above, almost white beneath. Length 6 mm. 



Vertex distinctly longer than in majusculus, passing the eye by about 

 one-fourth its length, anterior edge parabolic and obviously carinate; 

 median carina prominent, abbreviated before; hind edge almost truncate. 

 Pronotum shorter than vertex, carinae prominent. Mesonotal carinae 

 sharp, feebly arcuate at apex. The closed elytra almost parallel, a very 

 little wider toward their apex. Front narrower than in majusculus, not 

 obviously wider at apex, carinae prominent. Last ventral segment of the 

 male truncate at apex, without a median tooth, plates contiguous at base, 

 oblong, oblique at apex. 



Color a uniform obscure amber-brown, quite strongly tinged with 

 fulvous on mesonotum; surface of the elytral areoles subhyaline and 

 beautifully green-iridescent when closed over the wings. Beneath whitish, 

 tinged with fulvous or amber on the front, clypeus, mesopleura and apex 

 of the tarsi; lateral carinae of the front pale. 



Described from twelve examples, representing both sexes, 

 taken about the upper end of Fallen Leaf Lake and along Glen 

 Alpine Creek during July. i\Iost of these I beat from cypress 

 bushes and that probably is the native food-plant of the species. 



OUarus fidus Van D. One pair taken near Glen Alpine Creek 

 in July. These are a little larger and darker than those from 

 San Diego County but do not seem to differ otherwise.
