1. Hebrus major, n. sp. (Tab. VIII. fig. 1.) 
3. Rather elongate, robust ; head black, reddish on each side between the eyes and also at the sides in front, 
the pronotum and scutellum reddish-brown, the elytra brown, the clavus with a broad, wedge-shaped, 
evanescent, white patch at the base, the nervures of the corium blackish, becoming paler anteriorly, the 
membrane with a transverse pallid streak near the tip of the corium and a small oblong pallid streak 
before the apex; under surface blackish, the genital segments testaceous; the antenne and legs 
testaceous, the coxee and trochanters and the base of the femora flavous; the body, legs, and antenne 
finely pubescent, the venter thickly clothed with short pallid hairs. Head without distinct median 
groove; antenne long and slender, 5-jointed, 1 one-half longer than 2, 3 nearly as long as 1, 4 a little 
shorter than 2 (5 imperfect). Pronotum strongly constricted at the sides, deeply sulcate down the 
middle, the two lobes separated by a row of coarse punctures, the posterior lobe with a transverse 
punctured groove before the base. Scutellum with a fine median carina. Legs rather stout. First 
ventral segment broadly raised in the middle between the posterior coxe, closing the rostral groove 
behind, the following segments broadly flattened along the middle. Meso- and metasternal carine 
prominent. .

_ Hab. Mexico, Orizaba (Bilimek, in Mus. Vind. Ces.). 
One example. Differs from all the other species of the family known to me in 
the broadly raised intercoxal portion of the abdomen, as well as by its comparatively 
stout legs and large size. In the deeply sulcate pronotum and prominent sternal 
carine it approaches H. sulcatus. The antenne are imperfect.
