In Tetrapriocera and Patea the antennae are n jointed. In all the 
others they are io-jointed, except in Xylopertha and in one species of 
Bostrichus, where they have but nine joints. Tetrcipnocevci loiigicor)iis 
(— schwarzi Horn) is the only known species of that genus. Xyloper - 
tha is confined, as might be expected, to the subsiberian fauna of the 
Pacific coast, where it is represented by bidentata , declivis and suturalis , 
hitherto placed in Sinoxylon, which genus has the two basal joints of the 
antennal club short and transverse. Xylobiops is proposed for the Sinoxy- 
loii basillare, texatiwn , s extub er cul&tuni and flondcinutn of the present 
lists. Dinapate wright, /, the type and only known species of the genus, 
is the largest bostrichid known ; it will probably soon become extinct 
by reason cf the destruction of its food-plant for commercial purposes. 
Dendrobiella, gen. nov. 
This genus inhabits the warmer parts of the North American con¬ 
tinent and also the "Aest Indies; the species known to me may be iden¬ 
tified by the following characters:— 
* 
Elytial punctures distinct throughout the disk, except at the sides, where they are obso¬ 
lete, finer toward base, coarser posteriorly to the brink of the declivity, the latter 
smooth and impunctured as usual throughout the genus. 
Larger species, 5-5~6 mm. in length, blackish in color. sericans Lec. 
Smaller species, 4 mm. in length, rufo-piceous in color. quadrispinosa Lec. 
Elytral punctures rather fine and sparse but distinct toward base, becoming wholly 
obsolete toward the declivity. Male.— Head well developed, the surface flat¬ 
tened, polished, nude and finely, sparsely punctulate, bituberculose at the base of 
the \ ertex; eyes moderate, very prominent; antennae pale, longer than the width 
of the head, the first seven joints together scarcely longer than the first joint of 
the club, the tenth joint long and narrow. Prothorax wider than long, slightly 
narrowed anteriorly, broadly truncate at apex, the sides becoming parallel be¬ 
hind the middle ; apical asperities moderately coarse and obtuse at the sides; disk 
polished, finely, subimbricately punctulate toward the middle in more than basal 
half. Elytra shining, the pubescence rather long, fine, decumbent, fulvous and 
conspicuous; apical truncature flat and shining, the tubercles moderate, the lower 
more obtuse. Female .—Smaller than the male but nearly similar, except that 
the head is smaller, more convex, less shining, feebly convex, punctured, pubes¬ 
cent and devoid of tubercles. Length 4.3-50 mm.; width 1.75-2 1 mm. 
Texas (Brownsville). pubescens, sp. nov. 
Elytral punctures wholly obsolete, being feebly traceable only very near the base. 
Male .—Head moderate, flattened, becoming concave behind the frontal margin, 
minutely, sparingly puberulent, slightly shining, finely and rather closely punctu¬ 
late throughout; two small tubercles of the vertex on a transverse line through the 
posterior limits of the eyes; antennae but little longer than the width of the head, 
nearly as in pubescens. Prothorax much wider than long, feebly narrowed in
