from base to apex, a distinct oblique impression from the humeri, disc vaguely 

 costulate, the costse tuberculiferous, the tubercles with short, erect, black 

 scales; surface clothed with dark cinereous pubescence, with a narrow, white, 

 band acutely annulate to the front behind the middle; apices not obliquely 

 truncate. Length .16 — .24 inch; 4 — 6 mm. 



These notes are intended to supplement the original description 

 and are made from two finely marked specimens collected in Kansas 

 and Texas. The general outline resembles IIij})crplatys. 



Li. nebtilosus n. sp. — Form moderately robust as in aculifer but more 

 convex, surface with dark cinereous pubescence, elytra with a rather broad 

 but indistinct, angulate band of paler pubescence at the middle and a dark 

 spot each side. Antennae % a little longer than the body, joints 3 — 4 a little 

 longer than the next three. Thorax about one-fourth wider than long, not 

 narrowed at apex, sides slightly behind the middle with an obtuse tubercle 

 limited in front and behind by a slight lateral constriction of the thorax, disc 

 coarsely punctured, sparsely pubescent and with five moderately prominent 

 tubercles, that at the centre being larger and more prominent. Elytra gradu- 

 ally arcuately narrowed at apical third only, apices separately rounded, disc 

 moderately convex, not densely punctured, the punctures finer near the apex, 

 surface finely tricostate, the costse with distant tubercles with erect scale-like 

 hairs, pubescence of surface not very dense, dark cinereous vaguely clouded, 

 the basal fourth slightly paler and a jnoderately broad paler band angulate to 

 the front at middle, and an irregular sooty spot in front of the outer ends of 

 this band. Body beneath with cinereous pubescence, maculate. Femora cinere- 

 ous, maculate, tibiae at middle and tip annulate with black, tarsi cinereous, last 

 two joints black. Length .50 inch ; 12.5 mm. 



This species is remarkable in having the middle umbone of the 

 thorax quite strongly marked and the thorax less transverse than 

 usual. The antennae are less elongate than in planidorsus but more 

 so than acub'fer. The hind trochanters are simple. 



One % , western Nevada, collected by H. K. Morrison. 



It, terraicolor n. sp. — Form of aculifer, densely clothed with luteous 

 pubescence, elytra with faint darker cloud at the side and a common, narrow, 

 arcuate fascia slightly behind the middle. Front nearly flat. Antennae % a 

 little more than half longer than the body, joints maculate and annulate at 

 the articulations. Thorax twice as wide as long, truncate at apex and base, 

 sides very obtusely subangulate, disc moderately convex, the tuberosities 

 scarcely evident, the central umbone indicated by a circle of large punctures, 

 a row of coarse punctures along the apex and base and a few near the side. 

 Elytra formed as in aculifer, apices obliquely truncate, disc with four rows of 

 feeble tubercles which are larger near the base, a distinct oblique impression 

 behind the humeral umbone, surface densely pubescent, sparsely punctate, 

 the punctures a little coarser toward the sides. Body beneath very densely 

 finely punctulate and densely clothed with cinereous pubescence with small 

 denuded spots. Legs similarly pubescent. Length .34— .46 inch; 9 — 12 mm. 



This species might be mistaken for an aculifer in which the 

 asperities are feebly developed, but the thorax is differently tubercu-
