partments of the mesonotum and base of the elytra as far as the apex 

 of the scutellum pale cataueous ; beyond this on the closed elytra is a 

 broad transverse pale yellowish vitta, which is broader on the com- 

 missure where it touches the point of the scutellum and apex of the 

 clavus ; transverse nervures near the apex indistinctly paler ; ground 

 color of the elytra intensified next the pale transverse band. Abdomen 

 more or less fulvous. 



Described from one pair taken in copulation on Mt. Wilson, 

 California, September 14, 1908, by Mr. J. C. Bradley. This 

 species is very distinct by its yellowish color and the broad 

 transverse pale band bordered with castaneous, on the elytra. 



Gixius lepidus n. sp. 



Black, with the carina? marked with flavo-testaceous. Elytra whitish 

 hyaline, the base and a large stigma fuscous ; nervures strongly punct- 

 ured with fuscous. Length : male, 5 mm. ; female, 6h mm. 



Head well produced ; vertex almost quadrangular, its length about 

 equal to the width between the eyes ; passage to the front broadly 

 rounded, without the transverse apical compartment found in our 

 other species ; basal compartment almost an equilateral triangle, its 

 apex rounded, its surface depressed, punctured, with a median carina 

 at base. Front broad, but moderately narrowed at base ; median 

 carina distinct, third ocellus obsolete, apical suture strongly arcuated, 

 not at all angled in the female, scarcely so in the male ; color piceous, 

 becoming paler or testaceous at base, especially in the female. Clypeus 

 deep black, median carina paler, lateral carinas slender and scarcely 

 paler. Pronotum of equal length across its whole width ; pale brown- 

 ish-testacous, darker in the fovae, black under the eyes. Teguke 

 large and conspicuous, testaceous-white. Mesonotum black ; carinas 

 and hind margin of the scutellum pale in the female. Elytra hyaline 

 with a very decided milky cast ; a transverse band across the apex of 

 the scutellum which may include the whole basal portion of the elytra 

 and the large stigma, deep fuscous; veins strongly dotted, the trans- 

 verse nervure toward the base fuscous. Wings whitish hyaline with 

 slender brown nervures. Beneath black ; disk of the metapleura in 

 part fulvo-testaceous. Legs brown, the acetabulae, knees, and bases 

 of the tibial spines pallid. Sides of the genital segment of the male 

 broadly rounded, the ventral sinus broad, with a very short rounded 

 median tooth; plates very short, but little exceeding the sides of the 

 genital segment, ob-triangular or imperfectly fan-shaped at apex, 

 which is touched with whitish ; pygofers but little exceeding the plates, 

 subconical at apex, and including the fulvous anal tube. In the female 

 the apical projection of the pygofers is unusually large, slender and 

 acute at tip. In both sexes the lower surface and genital segment are 

 covered with a whitish tomentum.
