long and barely two-fifths as long as the elytra, minutely margined 

 toward the middle at base; scutellum ogival, much wider than long; 

 elytra much longer than wide, parabolic, the sides becoming more 

 parallel basally; micro-reticulation relatively rather coarse in wavy 

 broken transverse series; punctures of the three inner abbreviated 

 series and of the stria, relatively coarse, semicircularly lunate and 

 conspicuous; metasternum between the coxae very broad posteriorly, 

 smooth, narrowed anteriorly, the mesosternum smooth and moder- 

 ately developed; abdomen pointed at tip as in the preceding, the sex 

 of the type in each case probably female. Length 1.2 mm.; width 



0.7 mm. Louisiana (New Orleans) ludovicianus n. sp. 



22 Species of the Pacific coast. Body oblong-oval, only moderately 

 stout, shining, ochraceous, the combined elytra somewhat clouded 

 centrally; head fully half as wide as the prothorax; antennae rather 

 long and slender, of the usual structure, the sparse bristling setae 

 long, the club not as long as the funicle, in great part shining; pro- 

 thorax short, much more than twice as wide as long, the strongly 

 converging sides distinctly arcuate, the basal bead fine but evident 

 under ample enlargement; scutellum triangular, only slightly wider 

 than long; elytra much longer than wide, three times as long as the 

 prothorax, the sides parallel and feebly arcuate, becoming almost 

 circularly rounded in about apical half; strigilato-reticulation rather 

 fine, very feeble, not modifying the polished lustre; there are two or 

 three abbreviated inner series of semicircularly lunate and moder- 

 ately impressed punctures, those of the moderate stria minute, 

 feeble and indefinite; metasternum between the coxae nearly smooth, 

 subparallel, not very wide, the tumid and well developed mesoster- 

 num before it bearing a transverse corona of subdecumbent setae; 

 hind tibiae long, the hind tarsi slender, two-thirds as long as the 

 tibiae; abdomen obtuse at tip. Length 1.7 mm.; width 0.95 mm.

23 Punctures of the two inner abbreviated series and those along the 

 stria semicircular but widely spaced, and so shallow as to be un- 

 noticeable except under considerable enlargement; prothorax large. 

 Body not narrowly oval, obtuse behind, testaceous in color; head 

 scarcely half as wide as the prothorax, the punctures minute but deep 

 and rather numerous; antennae slender, the third joint long, cylindric, 

 equaling the next two combined, the club well developed, not much 

 dilated but longer than the funicle, glabrous, excepting the long 

 stiff setae on one side, in great part finely pubescent on the other; 

 prothorax less than twice as wide as long and about half as long as the 

 elytra, the converging sides evenly arcuate and the stria along the 

 base medially very fine; scutellum triangular, much wider than long; 

 elytra slightly longer than wide, bluntly parabolic posteriorly, the 

 sides becoming parallel toward base; strigilation very minute, close- 

 set and feeble, the impressed stria not very coarse; metasternum with 

 numerous asperate setigerous punctures; abdomen obtuse at tip;
