Sphindus Chev. 
The species of this genus are small and oblong, with duller surface 
lustre and moderately long, rather sparse pubescence, serial in arrange¬ 
ment on the elytra. The three species before me may be thus sepa¬ 
rated :— 
Antennal club 2 jointed. 
Antennal club purely 3-jointed. 
2— Pronotum minutely and ratter closely punctured, more or less rufo-piceous in 
color. Atlantic regions to Iowa. americanus Lec. 
Pronotum more coarsely and quite sp rsely punctured. Body black, stouter, dull in 
lustre ; head and eyes moderate in size, the epistoma polished ; antennm a little 
longer than the width of the head, the club only moderately stout, the tenth joint 
twice as long as the ninth ; prothorax nearly twice as wide as long, the sides just 
visibly convergent from base to apex, feebly arcuate ; apex broadly arcuate ; ely¬ 
tra scarcely a fourth longer than wide, barely wider than the prothorax and two 
and one-half times as long; serial punctures rather fine, the intervals dull and 
minutely shagreened. Length 1.9 mm.; width 0.9 mm. Colorado (Buena 
Vista-8000 feet). crassulus, s P . nov. 
3— Narrowly oblong, more shining, piceous black, the elytra, legs and antenme pale 
testaceous ; head moderate, the eyes large and convex, separated by about three 
times their own width ; antenna moderate in length, the last three joints forming 
a compact subcylindric club; prothorax much smaller than in the two pre¬ 
ceding species, transverse, the sides subparallel; surface evenly convex, very 
minutely and not very closely punctulate ; elytra two-fifths longer than wide, 
about a fifth wider than the prothorax and three times as long ; serial punctures 
feeble but distinct, the intervals smooth and alu'aceous; apex obtuse^ rounded 
as usual. Length 1.7 mm.; width 0.7 mm. Canada (Toronto). 
trlnifer, sp. nov. 
Americanus varies greatly in size as usual in this and neighboring 
families \ it is quite abundant and occurs in fungi of various species.
