ceous, the scales on the beak arranged in rows, the apical tufts dis- 

 tinct, and the thoracic scales condensed on the sides and along the 

 median line, giving thereby the appearance of a dark vitta each side 

 of median line. Readily distinguished from the preceding species 

 by its differently shaped and sculptured prothorax, and more elon- 

 gate, oval scales ; from pusio it differs by its elongate and not densely 

 crowded scales. From fratercidns, of the next group, with which it 

 agrees in size and appearance, it differs by the prothorax being wider 

 than long, the absence of antecoxal ridges and the rufous legs. It 

 agrees fairly well with the description of connivens Casey, but is 

 smaller and the rostrum of the female is not very slender or shining. 



S. respleii«lens u. sp. — Elongate, black, aiitennje and legs fuscous, densely 

 clothed with large, broadly oval, imbricate, yellowish white scales, having a 

 pearly lustre and completely concealing all sculpture of the surface. Beak stout, 

 very feebly curved, imperceptibly tapering from the base, about as long { "J, ) as 

 the prothorax, densely scaly in its basal two-fifths, shining and finely punctured 

 beyond, basal tufts prominent; scrobes scarcely oblique. Antennse inserted 

 about the middle ( % ), second joint not longer than the third, outer joints 

 scarcely wider, clava fusiform, densely pubescent. Head densely scaly. Pro- 

 thorax nearly one-half wider than long, strongly and rather suddenly narrowed 

 in front and broadly constricted at the apex, sides rounded, slightly convergent 

 behind, the scales have a greenish reflection and are intermixed with stout, erect 

 scales. Scutel punctiform. Elytra about one-fourth wider at the base than the 

 prothorax, elongate, fully twice as long as wide, sides straight, parallel for two- 

 fifths their length, then gradually rounded to the apex, strise entirely concealed 

 by the scales, when denuded of the latter rather well impressed, punctures ap- 

 proximate; interstitial setffi whitish, procumbent, interstices appearing slightly 

 concave with the scales intact, feebly convex, where denuded. Prosternnm 

 short in front of the coxfe, broadly emarginate, postocular lobes almost obsolete ; 

 femora very strongly clavate, tibiie rather stout, feebly biemarginate within, 

 apical hook distinct ; third tarsal joint feebly bilobed, fourth fully as long as the 

 two preceding joints together ; claws connate to the middle. Length 2.75 mm. ; 

 O.ll inch. 



Hah. — California. 



A single male specimen of this remarkable species in Mr. Ulke's 

 collection. An isolated form, the pearly lustre of its scaly vestiture 

 is not seen in any other species known to me. 



S. pusio Lee. — Elongate-oval, piceous, legs paler, very densely clothed above 

 and beneath with large, broadly oval scales, more or less matted together on the 

 upper surface, where they are of a dirty gray or grayish ochre color, paler and 

 less crowded beneath, except on the sternal side pieces. Beak in the male very 

 robust, rather strongly curved, tapering from base to apex, densely punctured, 

 with a median elevated line and striate each side from the base to the insertion 

 of the antennae, densely scaly on the basal third, basal tufts not prominent, 

 somewhat shining and remotely punctulate in its apical half; the basal constric-
