MYCETOPHAGIDyE 175 



than twice as wide as long, the sides converging and evenly arcuate 

 from base to apex, the two medial sinuses at base very feeble, the 

 surface even; elytra nearly one-half longer than wide, as wide as the 

 prothorax, rather narrowly rounded at apex, the sides arcuate, becom- 

 ing parallel only near the base; punctures and pubescence confused 

 throughout ; hind tarsi longer than the tibiae. Length ( 9 ) 1.65 mm. ; 



width 0.78 mm. New Mexico (Las Cruces) longulus n. sp. 



Prothorax in great part pale in color 2 



2 Body more broadly oval than in the preceding, convex, more shining, 

 the punctures above smaller, sparser and less asperate, fine and dense 

 beneath; pubescence coarse, reclining, rather long and pale in color; 

 head somewhat more than half as wide as the prothorax, the eyes 

 small; antennae moderate, rather slender, the club relatively more 

 slender than in longulus, the ninth joint longer than wide, the tenth 

 slightly wider than long and the eleventh quadrate; prothorax, 

 more than twice as wide as long, the converging sides somewhat 

 strongly arcuate; surface black, with broad pale periphery throughout 

 the base, apex and sides in the more mature stage, the black some- 

 times nubilously pallescent; elytra scarcely more than a third longer 

 than wide, about three times as long as the prothorax, oval, more 

 obtuse at apex than in the preceding; pale areas greatly exceeding the 

 black, the basal pale fascia with a posterior projection along the 

 suture, the post-medial fascia more even, bent posteriorly toward the 

 suture and, between the two fasciae on the outer side, there is a pale 

 spot, generally obliquely uniting with the basal fascia; apical pale 

 fascia anteriorly emarginate at the suture; hind tarsi (9) a little 

 longer than the tibiae. Length (cf 9 ) 1.5-1.75 mm.; width 0.68-0.85 

 mm. Pennsylvania to Utah (Provo). Eight examples. 



nebulosus Lee. 



Body more elongate-elliptic in form, similarly convex, more shining and 

 very pale flavo-testaceous in color throughout, the elytra with faintly 

 darker markings, outlining the three broad fasciae of the usual type 

 of ornamentation; pubescence shorter and more closely decumbent 

 than in nebulosus, sparser and much less conspicuous, the punctures 

 of the upper surface throughout much coarser and more deeply 

 impressed; head slightly larger, the eyes similarly small, the hairs 

 directed outwardly as usual; antennae nearly as in nebulosus; pro- 

 thorax nearly as in that species in outline and much more than 

 twice as wide as long, but very pale in color throughout; scutellum 

 transversely rounded; elytra longer, nearly one-half longer than 

 wide, rather more than three times as long as the prothorax and equal 

 to the latter in width, obtusely rounded at apex; under surface 

 closely and strongly punctured; hind tarsi much longer than the 

 tibiae, very slender. Length (9) 1.7 mm.; width 0.8 mm. New 

 York (Catskill Mts.),- H. H. Smith pallens n. sp. 



The two specimens of pallens at hand are alike in every way, but 

 nevertheless may be somewhat immature, though there is no in- 

 dication of this by warping of the integuments; at any rate.it is
