THE CA>fADIAN ENTOMOLOGIST. 265 



by Mr. J. C. Bradley. This species may be known by the subconical 

 head, resembling that found in Paracceiidia in the Jassidfe, the uniformly 

 brown or testaceous-brown colour sometimes tinged or marked with san- 

 guineus in places, and the pale veins on the infuscated apex of the elytra. 



CATONIA NERVATA, n. Sp. 



Form and size of dimidiata, but with a shorter and broader vertex. 

 Colour a clear fuscous-brown, elytral nervures and all carinas, except those 

 of the head, whitish ; base of the clypeus with a whitish mark on either 

 side. Length, 5)4 mm. 



Head very short and blunt ; at apex rounded in both diameters. 

 Vertex transverse, its length scarcely one-half the width between the eyes, 

 sloping and confused with the rounding base of the front ; carinte incon- 

 spicuous, forming a transverse compartment rounded before and a little 

 longer at the middle than next the eye ; hind edge feebly arcuated. Front 

 broad, a little constricted between the eyes ; the carina distinct below, 

 obsolete on the tumid base \ apex rather deeply angularly excavated to 

 receive the clypeus ; the latter longer than broad, with prominent median 

 carinse and narrowly expanded margins. Viewed from the side, the base 

 of the front is but feebly, conically produced, with the lateral carina; 

 closely following the contour of the eyes, as in rubella. Pronotum shorter 

 than the vertex, deeply angularly emarginate. Mesonotal carinae distinct, 

 parallel. Median tooth of the male genital segment slender and acute, 

 over one-half the length of the plates. 



Colour clear fuscous brown, a little tinged with castaneous on the 

 mesonotum ; carin?e of the pro- and mesonotum broadly whitish, the 

 lateral angles of the latter ivory-white. Vertex and front more testaceous- 

 brown, an oblique mark on each side of the base of the clypeus and its 

 apex pallid, pleural pieces broadly edged with whitish ; legs pale 

 testaceous-brown ; abdomen blackish-fuscous, the slender edges of the 

 segments and genital pieces pallid. Elytra fuscous-brown, becoming 

 paler along the middle of each areole ; nervures strong, mostly whitish, 

 but somewhat alternated by dusky in places, the transverse and apical more 

 conspicuously white. Wings a little infuscated at apex with dark nervures. 



Described from one male taken on Mt. Wilson, near Pasadena, 

 California, on August loth, 1909, by Mr. Fordyce Grinnell, jr. This 

 species is very distinct from any other known to me, and is well charac- 

 terized by the clear fuscous-brown colour veined with whitish. Allied to 

 Pledoderes lineaticollis Fowler, but with a shorter vertex and immaculate 

 front.
