near sutural margin ; behind this spot a narrow vitta extending along 

 sutural margin to apex ; and a minute spot on middle of elytron at 

 apical fourth. 



Abdomen beneath vaguely granulose, sparsely marked with trans- 

 verse, crenulate lines, which are coarser on basal segment, sparsely, 

 finely punctate, sparsely, uniformly clothed with short, recumbent, 

 white hairs, and the third and fourth segments ornamented on each 

 side with a spot of dense, yellowish-white pubescence; first segment 

 strongly convex at middle, the suture between first and second seg- 

 ments not indicated at the sides; last segment broadly rounded at 

 apex ; vertical portions of the segments densely clothed with recum- 

 bent, yellowish- white pubescence, except the second, which is gla- 

 brous ; pygidium densely granulose, sparsely, coarsely punctate, with- 

 out a projecting carina at apex. Prosternum rather coarsely, sparsely 

 punctate, sparsely clothed with moderately long, semierect, white 

 hairs; prosternal lobe broad, slightly declivous, broadly, arcuately 

 rounded in front; prosternal process broad, the sides parallel to 

 l*ehind the coxal cavities, then obliquely narrowed to the apex, which 

 is acute and bent downward. Mesosternum, metasternum, and poste- 

 rior coxae densely clothed at the sides with long, recumbent, yellow- 

 ish-white pubescence. Tibiae slender, unarmed at apices, the ante- 

 rior pair feebly arcuate. Posterior tarsi slightly shorter than tibiae ; 

 the first joint slightly longer than the following two joints united.

Length, 8.5 mm ; width, 2.1 mm. 



Type locality. — Tejupilco, Mexico, D.F. 



^y^e.— U.S.N.M. No. 49568. 



Remarks. — Described from a unique female collected at the type 

 locality at an altitude of 3,960 feet, during July 1932, by H. E. 

 Hinton. 



This species is more or less closely allied to alhofasciatus Water- 

 house, but it differs from that species in having the head broadly 

 depressed in front, the pronotum more broadly depressed at middle, 

 the elytra uniformly dull reddish-cupreous, and each elytron orna- 

 mented with a narrow, yellowish-white, pubescent vitta along the 

 sutural margin at apical fourth. 



AGRILUS MONTEZUMA, new species 



Male. — Elongate, slender, rather strongly flattened above, rather 

 strongly shining; head aeneo-virideous, becoming reddish cupreous 

 on occiput; pronotum reddish cupreous; elytra black, with a vague 

 purplish tinge; beneath cupreous, with a more or less distinct 

 aeneous or reddish reflection in certain lights.
