Coleopterological Notices, V. 587 



Falvipenne Say, is not by any means a variety of coquus, but is 

 si)ecifically distinct. Goquvs Liun. has the pronotum in the male 

 rather coarsely punctured throughout, except near the base, but in 

 tlie female very finely extremely densely so; this character may 

 also be common to the other allied species, but cannot be verified 

 at present because of their denser and longer vestitiire. The sexual 

 disparity of armatum in pronotal sculpture is very remarkable. 



T. niiripeiine n. sp. — Parallel, convex, black, tlie elytra bright aureo- 

 fulvous except at tlie basal margin ; pubescence dense, assuming the color of 

 tlie integuments, recumbent on the elytra where it is dense and arranged 

 oliliquely on the strong corrugations but x^-ry inconspicuous in the intervals, 

 erect on the pronotum where it is short, not concealing the surface sculpture. 

 Htad moderate, densely punctate, the antennal prominences acute ; antenna 

 vt-ry slender, about one-half longer than the body, basal joint oval, twice 

 as long as wide, three-fifths as long as the third, second slightly longer than 

 wide, four to seven equal, a little shorter than the third, eleventh with the 

 appendage as long as the basal part and feebly bent at apex. Prothorax a 

 little wider than long ; apex slightly wider than the base, the acute and 

 prominent lateral tubercles slightly behind the middle; disk opaque, feebly 

 and finely 5-tuberculate, the median tubercle larger and polished ; punctures 

 coarse, very dense, abruptly fine and extremely dense near the base. Scutel- 

 lum. roughly punctate. Elytra three times as long as wide ; sides parallel, the 

 humeri obtusely prominent; apex conjointly broadly rounded; disk of each 

 with five strong narrow ridges, the fourth joining the fifth before the middle. 

 Legs slendei-, the posterior much longer, with the tiliije soniewliat dilated and 

 compressed. Length 14.0-20.0 mm. ; width 3.8-5.7 mm. 



Utah (southwestern); Arizona. 



The three specimens in my cabinet are males and I have not seen 

 the female. This species is somewhat smaller than coquus, but all 

 the species vary enormously in size. 



Among the eleven specimens of coquus in my cabinet there are 

 only three females; the elytral corrugations in that species are 

 always much wider and more feeble than in fulvipenne ; the form 

 of the hind tibiae will however distinguish them at once. 



BAT¥LE Thom. 



B. cylindrella n. sp. — Narrow, cylindrical, polished, bright red 

 throughout, the elytral suture not darker, post-sterna blackish ; legs pale, 

 the tarsi black except near base and apex ; antennae rufo-testaceous, dark 

 toward apex especially toward the apices of the joints ; vestiture very sparse, 

 coarse, erect, not very long, pale luteous in color. Head finely, remotely 

 punctate, almost completely impunctate before the antennae, the latter slender.
