64 MEMOIRS ON THE COLEOPTERA 



basally, the punctures very minute and feeble throughout, but with 

 the minute slender decumbent hairs unusually obvious; prosternum 

 formed as usual, the three to five terminal setae rather long; meso- 

 sternum abruptly declivous from the tip of the metasternal process, 

 its upper line tumid; hind tarsi unusually short, scarcely more than 

 half as long as the tibiae. Male not observed. Length 1.2-1.4 nim.; 

 width 0.75-0.88 mm. Long Island, westward to Nebraska, Kansas 

 and Texas (Galveston). Abundant and very uniform in size. 



\Phalacrus nitidus Mels.] nitidus Mels. 



Body elongate, much larger, the elytra cuneiform, with not very broad 

 but obtuse apex; color pale rufo-testaceous throughout; head large, 

 much more than half as wide as the prothorax, the minute punctures 

 unusually close-set and distinct; antennae as usual, except that the 

 club is larger than in any of the preceding species, not especially 

 broad but longer than the entire funicle; prothorax less than twice 

 as wide as long, very convex, the moderately converging sides not 

 very arcuate, the base not at all margined at the middle; scutellum 

 transverse, triangular; elytra much longer than wide but barely 

 more than twice as long as the prothorax, the surface smooth and 

 highly polished, the wavy strigilation so minute, close-set and feeble 

 as to be scarcely glimpsible, even under high power and totally 

 obsolete broadly toward base; stria not very coarse; punctures every- 

 where extremely minute; prosternal process with seven or eight short 

 stout setae; mesosternum only moderate in length before the meta- 

 sternal process; abdominal hairs short and very stiff. Length 1.8 

 mm.; width i.i mm. Florida (Sand Point). A single female 



example convergens Csy.

Prosternal process with four setae 22 



Prosternal process with more than four setae 25 



21 Body minute, evenly oval, obtusely rounded behind, polished, tes- 

 taceous; head rather more than half as wide as the prothorax, the 

 antennae slender, the third joint only between two and three times as 

 long as wide, swollen apically, slender at base, the club fully as long 

 as the funicle; prothorax slightly more than twice as wide as long, 

 the strongly converging sides evenly and rather strongly arcuate, 

 the base finely and feebly margined medially; scutellum triangular, 

 much wider than long; elytra slightly longer than wide, parabolic in 

 outline, micro-reticulate in broken wavy lines, the retriculation not 

 very minute; punctures of the two inner series and the stria, medially, 

 very small, not conspicuous under the hand lens; stria deeply 

 impressed, not very coarse; metasternal process smooth, narrowing 

 anteriorly, with the mesosternum moderately developed before it. 

 Length i.o mm.; width 0.63 mm. Virginia (Fort Monroe). 



trisetosus n. sp. 



Body barely larger and rather stouter than in the preceding, otherwise 

 nearly similar; head much more than half as wide as the prothorax, 

 the antennae nearly as in trisetosus, except that the club is scarcely 

 as long as the funicle; prothorax nearly similar but actually and 

 relatively much shorter, being two and one-half times as wide as
