before the coxse, the widely separated middle coxse, the modified 

 hind tibia? in the male, and the angulate fifth ventral in the female 

 are all characters either peculiar to this species or but faintly indi- 

 cated elsewhere. 



C. salpiiigoides Mots.— Elongate, parallel, subdepressed, shining, pieeous 

 brown, humeri faintly rufous, legs and antenna? brown ; pubescence obscure in 

 color, short and much inclined. Head sparsely, finely punctate; eyes moderate, 

 tempo ra short but distinct. Antenna? nearly reaching the hind margin of the 

 prothorax, joints 8-10 fully as wide as long. Prothorax subcordate, distinctly 

 wider than long, sides moderately rounded in front, convergent posteriorly, 

 faintly sinuate before the hind angles, which are distinct and a little obtuse; 

 margin finely serrulate; surface moderately punctate, basal fovea moderately 

 deep and somewhat produced laterally. Elytra elongate, subparallel, sides 

 broadly rounded ; stripe feebly impressed, punctures 7iioderate, those of the inter- 

 vals finer. Beneath sparsely punctate, the punctures of the presternum largest, 

 those of the metasternum finer; ventral segments very finely and sparsely punc- 

 tulate throughout. Presternum a little less than twice as long before the coxa; 

 as the coxal length : middle coxa? distant slightly more than one-half the coxal 

 width. Metasternum longer than the first ventral at sides, hut not evidently so 

 along the median line. Legs moderately slender. 



Male. — Not seen. 



Female. — Tibia? simple; fifth ventral but little shorter than the two preceding 

 united, and with a somewhat ill-defined apical impression. 



Length 2.4 mm.

It is by no means certain that this is the true salpitig aides, but the 

 description applies very well in a general way, except as to size — 

 Motschulsky's measurements indicating a species a little under 2 mm. 

 in length— and I have chosen to use this name rather than coin a 

 new one. Salpingoides was described from California. 



The species above characterized is nearest planula, with which 

 indeed it agrees well in color, sculpture and general form. It is, 

 however, distinctly less depressed, the prothorax is less strongly cor- 

 date and is a little more transverse, the presternum is shorter before 

 the coxae, the middle coxse are less widely separated, the metaster- 

 num is relatively shorter, and the fifth ventral of the female is 

 longer and differently formed. 



< . col ii Biil»ia sp. nov. — Oblong-ovate, moderately shining, pieeous brown, 

 humeral umbones a little paler, legs and antennae rufous; pubescence recumbent, 

 short, pale and inconspicuous. Head sparsely, finely punctate; eyes moderate; 

 tempora short but distinct; antenna? not quite reaching the hind margin of flic 

 prothorax, the eighth joint as wide as long, the ninth and tenth a little trans 

 verse. Prothorax subcordate, widest hut little before the middle, sides rather 

 strongly rounded anteriorly, nearly straight and moderately convergent poste-
