588 Coleopterological Notice's, IV. 



deeply excavated and having a very stout acuminate erect process 

 before each coxa ; in the female flat, without trace of impression; 

 anterior coxae separated by three-fourths of their own width. 

 Length 2.5-2.7 mm. ; width 1.3 mm. 



The two specimens before me are from New Jersey and Indiana. 

 It is somewhat singular that Dr. LeConte should have failed to see 

 the corneous prosternal processes in the male of this species; they 

 are quite conspicuous and must have been concealed by the anterior 

 femora in the specimens which he examined. 



15 CeiltrillUS exulans n. sp. — Rather broadly rhomboid-oval, convex, 

 piceo-rufous throiighoiit and densely clothed with scales, wliich are narrower 

 and yellowish in the middle three-fifths of the pronotnm, winter and denser 

 at the sides and also on the elytra near and especially behind the sciitellum. 

 Head rather coarsely, densely punctate, dull and squamulose, the impression 

 almost completely obsolete ; beak somewhat stout, short, evenly cylindrical, 

 smooth toward apex but densely punctate, rugose and squamose toward base, 

 evenly, rather strongly arcuate and not quite as long as the head and pro- 

 thorax ; antennffi inserted distinctly behind the middle, the scape as long as 

 the next four joints, first funicular joint fully as long as the next three, second 

 about equal to the succeeding two, club moderate, ovo-conoidal. Prothorax 

 short and transverse, four-fifths wider than long, the sides evenly, strongly 

 arcuate and convergent from base to apex, becoming parallel near the former 

 and 'feebly sinuate near the apex, which is transversely truncate and dis- 

 tinctly less than one-half as wide as the base, the latter straight and trans- 

 verse, the median lobe one-third of the total width, rounded and prominent ; 

 disk not very coarsely, deeply, densely punctate, the impunctate line feebly 

 traceable and extremely fine. Scutellnm moderate, squamose, slightly trans- 

 verse. Elytra slightly wider than the prothorax and fully twice as long, the 

 outline almost evenly ogival from base to apex, the latter acutely rounded ; 

 humeral callus quite distinctly prominent; disk rather finely, deeply striate, 

 the intervals wide, fiat, densely and confusedly punctate. Abdomen very 

 densely punctured and squamose throughout. Prosternura nearly flat, sepa- 

 rating the coxse by appreciably less than their own width. Length 3.3 mm. ; 

 width 1.6 mm. 



New Mexico (Gallup). Mr. Wickham. 



The single specimen is a female, but the species is very distinct 

 and allied only to perscitus. It differs from p)erHcitus in its much 

 larger size and stouter form, in the decidedly shorter relative length 

 of the intermediate and posterior tibia^., and in the pronotal punc- 

 tures which are here very close but circular in outline and not in 

 actual contact, while in perscitus they are coarser and polygonally 

 crowded. These two species belong to a peculiar type, distinguished 

 from the other allies of perscillus by the very much shorter, stouter 

 and evenly cylindrical beak.
