one-half wider than the prothorax," which is not the case in any of 

 the specimens before me. It is a distinct species, not very closely 

 related to any other known to me and easily distinguished by its 

 robust form, deep constriction of the thorax, general hirsute appear- 

 ance and narrow third tarsal joint. One of my specimens has a 

 sutural line and a vitta on each elytron white. 



S. iiiiicidus n. sp. — Elongate oblong, black, legs rufopiceous; densely 

 clothed above and beneath with moderately large, gray, oval scales. Beak mod- 

 erately stont, curved, about as long as head and prothorax in the male, a little 

 longer in the female, tapering from base to apex; in the male rather densely 

 punctured, striate and scaly from base to the insertion of the antennae, feebly 

 shining and remotely punctured beyond ; in the female densely, but more finely 

 punctured, scarcely striate with an indistinct, median, elevated line from base 

 to the antennal insertion, shining and scarcely punctured beyond; basal tufts 

 prominent, constriction profound ; scrobes scarcely oblique. Head finely rugu- 

 lose, front punctured, scaly; antennse rather slender, second joint of funicle 

 one-half longer than the third ; outer joints transverse, club v^-ider, densely 

 pubescent. Prothorax nearly one-half wider than long, about one-half as wide 

 at the apex than at the middle, rather strongly rounded on the sides in front, 

 broadly but feebly constricted at the apex, nearly straight and slightly conver- 

 gent on the sides behind the middle; surface closely and somewhat coarsely 

 punctured, .scales intermixed with large, suberect, squamiform setie : scutel very 

 small, scaly. Elytra oblong, two-fifths and rather suddenly wider at the base 

 than the prothorax, humeri prominent, declivous at the base, sides inconspicu- 

 ously narrowed behind the latter, sides nearly straight for three-fifths their 

 length, then broadly rounded to the apex, striae fine, not deeply impressed, punc- 

 tures remote, very small, nearly invisible, interstitial setse quite disrinct, brown, 

 hair-like; humeral prominence and a short basal line on the third interspace 

 white, prosternum rather deeply emarginate, transversely impressed, postocular 

 lobes prominent; femora slender, scarcely clavate, tibiae parallel from about the 

 middle, terminal hooks small ; tarsi slender, third joint broadly bilobed, fourth 

 long, projecting about the length of the preceding joint; claws small, slightly 

 divergent, connate beyond the middle. Length 3.25 — 3.5 mm. ; 0.13 — 0.14 inch.

Two specimens, male and female are before me. Readily recog- 

 nized by its uniform gray color and white line on the base of the 

 third and .seventh interspace, the femora are less clavate than in any 

 of the neighboring species. From intricatus it differs by its elongate 

 and nearly parallel form, the broadly bilobed third tarsal joint and 

 less hirsute appearance. A specimen in my collection from Califor- 

 nia I refer with some hesitation here ; it has the prothorax nearly 

 as long as wide and more strongly rounded on the sides. 



S. perplexu** u. sp. — Elongate oblong, pitchy black, densely clothed above 

 and beneath with small, broadly oval or rounded scales, blackish above, mottled 

 with white spots on the elytral disc; a broad, irregular stripe on each elytron of
