carinae white, the surface closely and minutely pale pubescent, omitting a 

 line either side next the lateral carinae; the prominent tylus pale; buc- 

 culje large, white, becoming infuscated at apex. Antennas and legs fulvo- 

 testaceous, the fourth antennal segment black on its apical two-thirds. 

 Femora and tibiae with an obscure dark median cloud, tarsi fuscous. 

 Rostrum pale, darker at apex. Pronotum deeper fulvous on its disk, 

 paler anteriorly and posteriorly, marked with fuscous in the anterior im- 

 pressions; carinae white, the median marked with black on the crest and 

 near the tip, the lateral with a fuscous mark behind. the middle and some- 

 times another on the crest. Closed elytra with a common large, nearly 

 round, brown cloud on their disk, darker anteriorly; the veins on the 

 reflexed sides of the pronotum, on the costal area and on the apex of the 

 sutural area and membrane mostly fuscous or black, the disk of the mem- 

 brane with a few vermiculate fuscous lines; extreme base of the discoidal 

 area infuscated. Beneath with a fuscous longitudinal vitta on either side, 

 sometimes indistinct. 



Described from five females taken by me with their young 

 on the margins of Clear Lake in Lake Co., August 3, 1916; 

 one taken by me at Lakeside, San Diego Co., October 2, 

 1913, and four taken by Mr. Giffard in San Joaquin Co., 

 May 25, 1917.

Our four North American species of this genus may be 

 distinguished as follows : 



Costal area of the elytra with two complete series of areolae 1 



Costal area of the elytra with three complete series of areolae 2 



1. Color brown, obscurely veined with fuscous, the reflexed portions of 



the pronotum infuscated; inhabits eastern states /'/t-.ra (Say). 



-. Color cinerous varied with fuscous, the disk of the pronotum and be- 

 neath fulvous or pale ferruginous; inhabits western states 



ornate, new species. 



2. Color nearly uniform ferruginous-brown, rostrum not surpassing the 



mesosternum brevirostris O. & D. 



-. Color cinerous varied with fuscous; rostrum attaining the hind mar- 

 gin of the metasternum variegata Pshly. 



66. Leptoypha minor McAtee? One example taken by Mr. 

 Giffard at Witter Springs differs from McAfee's description in 

 being larger, 2.4 mm., in having the third antennal segment 

 paler, especially at apex, not "infuscated" as indicated by 

 McAtee, and in a different infuscation of the upper surface, 

 the latter character probably of little or no significance.
