third wider llian tlie head and equally transverse, the apex but little 

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

 transTerse impression before the scutellura; elytra nearly a fourth 

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

 closely punctate; abdomen subparaUel, narrower than the 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 the middle, the meta- 

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

 0.S2 mm. California fSta. Cruz Mts.) franciscana 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 picata type. 



Cbilopora Kr. 



Form slender, subparaUel, strongly convex, shining, dark red-brown in 

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

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

 pubescence short, incouhpicuous, fine, moderately dense but scarcely 

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

 and obliquely constricted 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 

 €leventh obtusely poioted 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, feebly 

 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 ihe 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; 

 middle 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 

 mm.; width 0.7 mm. New York (Peekskill) americana n. sp. 



Form 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, 

 extremely minutely, subgranularly and densely punctate, the ab- 

 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, 

 rounded at the sides of the base, the eyes not at all prominent; antennae
