third wider than the head and equally transverse, the apex but little 

 narrower than the base; surface finely, sparsely punctate, with a small 

 transverse impression before the scuteJlum; elytra nearly a fourth 

 wider and one-half longer than the prothorax, less finely and not so 

 closely punctate; abdomen subparallel, narrower than th« elytra, nar- 

 rowed slightly posteriorly only near the apex, similarly finely and 

 sparsely punctate throughout and with the first three tergites narrowly 

 and deeply Impressed at base; middle coxae contiguous, the mesosternal 

 process acutely angulate but only extending to tbe middle, the meta- 

 sternum still more obtusely abbreviated. Length 3.2 mm.; width 

 0.82 mm. California (Sta. Cruz Mts.) franeiscana n. sp. 



These species both have the prothorax much more devel- 

 oped than in the more northern vancouveri Csy., and agree 

 nearly with European species of the picaia type.

5'orm slender, subparallel, strongly convex, shining, dark red-brown in 

 color, the head and abdomen behind the third segment blackish; legs 

 pale brownish- flavate, the antennae infumate, gradually pale basally; 

 pubescence short, inconspicuous, fine, moderately dense but scarcely 

 sericeous on the abdomen; head fully as long as wide, parallel, abruptly 

 and obliquely consiricted at base, the eyes slightly prominent, the 

 punctures fine and sparse, the surface polished; antennae long, extend- 

 ing to about the tips of the elytra, slender toward base but gradually 

 rather strongly incrassate distally, the tenth joint longer than wide, the 

 eleventh obtusely pointed and as long as the two preceding combined; 

 prothorax but little wider than the head, distinctly longer than wide, 

 widest at about apical two-fifths, the sides broadly rounded, feebiy 

 converging and straight toward base, the latter much wider than the 

 apex; surface finely, sparsely and subgranularly punctate with polished 

 Interspaces, except rather narrowly along the middle, where the punc- 

 tures are dense and the surface feebly impressed toward base behind 

 the middle; elytra about a third wider and a fourth longer than the 

 prothorax, finely, closely punctate; abdomen parallel, slightly narrower 

 than the elytra, extremely minutely and rather closely punctulate; 

 middl-e coxae contiguous, the mesosternal process very acutely angu- 

 late, extending to about the middle, the metasternum short but rather 

 acutely angulate, the long Isthmus acutely compressed. Length 3.8

'J'orm slender, convex, blackish-castaneous in color, the head and posterior 

 part of the abdomen black; legs slender, pale flavate, the antennae 

 black, becoming piceo-testaceous toward base; integuments opaque,

 domen still more minutely but simply and very closely punctulate, 

 less minutely and closely in the three basal depressions, the pubescence 

 short, very close, especially on the abdomen; head as long as wide,
