9O MEMOIRS ON THE COLEOPTERA 



angles subequal and evident; surface coarsely, polygonally punctured 

 but not subbasally impressed, each puncture bearing a short and very 

 thick bristle; scutellum very small, not as wide as long, truncate at tip; 

 elytra barely two-thirds longer than wide and a third wider than the 

 prothorax, parallel, with feebly arcuate sides and truncate apex, the series 

 of rather coarse punctures as in parallela; pygidium ( 9 ) wider than long, 

 with narrowed and arcuato-truncate apex and very coarse punctures; 

 abdomen with the basal segment as long as the next three. Length ( 9 ) 

 1. 68-1. 8 mm.; width 0.52-0.55 mm. Three examples, unlabeled in the 

 Levette collection, but probably from Colorado. 



Allied to parallela Lee., but smaller and shorter, especially with 

 less elongate elytra and with very much larger eyes ; the thick erect 

 pale setae are everywhere rather shorter and less conspicuous than 

 in parallela, and the female pygidium is shorter and more truncate 

 at tip. It resembles parallela in the obsolete thoracic impressions. 



Monotoma quadraria n. sp. Form rather slender and nearly parallel, 

 subopaque, the type pale testaceous in color throughout, the setae very 

 thick and yellowish; head unusually small, much narrower than the pro- 

 thorax, coarsely, closely punctate, with a feeble ambient impression along 

 the sides and base, the median part broadly and evenly convex; eyes 

 small; antennae extending to the middle of the prothorax, the ninth 

 joint evidently larger than the eighth and fully half as wide as the club; 

 prothorax very distinctly elongate, with straight and feebly subcrenulate 

 sides, the apex distinctly narrower than the base; angles having a slightly 

 greater reflexion of the edge but hardly nodiform, the anterior somewhat 

 prominent and with thickened edge; surface with two distinct subbasal, 

 and two very feeble and indefinite subapical, impressions, those on the 

 same side not connected in any way and widely separated; punctures 

 coarse, crowded laterally, distinctly separated dorsally; scutellum as 

 usual; elytra nearly four-fifths longer than wide and barely a fifth or sixth 

 wider than the prothorax, opaculate, the punctures serial, coarse and 

 close-set, the lines of pale setae very regular; pygidium nearly as long as 

 wide, triangular, with rounded angle, the punctures very coarse apically, 

 smaller and more sharply defined basally, everywhere well separated. 

 Length (9) i-75 mm.; width 0.55 mm. California (San Francisco). 



A very distinct species, which I long had marked quadrifoveolata 

 Mots., in my collection. I am unable to refer to the original de- 

 scription, giving Daghestan as the locality, but, according to the 

 description of Horn, from a District of Columbia example, it does 

 not closely resemble the European species, except in its ferruginous 

 color and opaque surface, for there is no trace of the longitudinal 

 grooves connecting the pronotal impressions, and the anterior im- 

 pressions are so feeble and diffused in quadraria that they cannot 

 be observed, except under oblique illumination. Quadrifoveolata,
