1. Zascelis irrorata. (Tab. XXVI. figg. 8, 3a; 34, hind leg.) 
Zascelis irrorata, Lec. Proc. Am. Phil. Soc. xv. p. 257°. 
Elongate-ovate, rather dull, piceous or nigro-piceous, the antenne and the tibial carina ferruginous ; sparsely 
clothed with narrow, intermixed, cinereous and ochreous scales, which are clustered into small patches 
on the elytra and on the basal lobe of the prothorax. Head densely punctate, the eyes depressed and 
widely separated ; rostrum strongly curved, almost reaching to the metasternum, rather slender, a little 
thickened towards the base, closely punctate, except along the smooth median line, the punctuation 
becoming dense and rugose at the base, the antennew inserted at the middle, joint 2 of the funiculus 
shorter than 1, the club ovate. Prothorax broader than long, rapidly narrowing from the middle, the 
sides rounded anteriorly, the base strongly bisinuate; densely, rather coarsely punctate, except along the 
smooth raised median line. Elytra a little wider than the prothorax, narrowing from the middle, flat- 
tened on the disc, the humeri obtuse ; with rows of coarse oblong punctures placed in broad shallow strie, 
the interstices flat on the disc, convex towards the sides and apex, closely, subseriately punctate, the 
punctures in the dorsal series limited on each side by a smooth raised line. Beneath coarsely, closely 
punctate. Metasternum and first ventral segment depressed down the middle in the ¢. Femora feebly 
dentate. Tibie strongly carinate, the carina on the intermediate and posterior pairs more or less notched 
along its outer edge, becoming bidentate at the apex. Tarsal claws slender. 
Length 6-64, breadth 25—2,9, millim. 
Hab. Norta America, California, Nevada, and Colorado !.—Mxxico (Mus. Brit.), 
Pinos Altos in Chihuahua (Buchan-Hepburn) ; GuaTEMALA, near the city (Champion). 
Five specimens, agreeing fairly well with Leconte’s description, so far as it goes. 
Very like Cryptorhynchus geminatus, Boh., from Brazil, but narrower, and with the 
eyes more widely separated, the rostrum longer, the prothoracic sculpture not so coarse, 
the interstitial punctuation of the elytra much denser and finer, the rostrum more 
elongate. 
2. Zascelis carinipes, sp.n. (Tab. XXVI. figg. 4; 4 a, hind leg.) 
Elongate-ovate, shining, black, the antenne obscure ferruginous, the outer tibial carina fulvous; somewhat sparsely 
clothed with rather coarse, narrow, ochreous scales, which are here and there clustered into small fascicles 
on the prothorax and elytra. Head rugosely punctate, without sulcus near the eyes, the latter depressed 
and moderately distant ; rostrum rather slender, a little widened towards the base, curved, as long as the 
head and prothorax, rugosely punctate and 5-carinate in its basal half, and sparsely punctate thence to 
the tip, the apical half slightly smoother in the 2, the antennew inserted near the middle, joints 1 and 2 
of the funiculus equal in length, 3-7 short, together scarcely as long as the oblong-ovate club. Prothorax 
transverse, much narrowed in front, the sides rounded almost from the base, the latter bisinuate ; densely 
punctate, sometimes obsoletely carinate in front. Scutellum oval, smooth. Elytra a little wider than the 
prothorax, subparallel at the base and gradually narrowed thence to the apex, flattened on the disc ante- 
riorly ; with rows of coarse, subquadrate, approximate punctures separated by narrow, raised, rugulose 
interstices. Beneath coarsely punctate. Legs short and stout ; femora sharply dentate, the tooth on the
