longitiidiii.'il inipiession on the posterior e<lgi', iiiid the second 

 has a lateral stria ; the anterior tibijo are 4-deutate.

ChRONUS, gen. nov. 



Body oval in outline, microscopically punctulate above and 

 below ; head flat above, not iuipressed, frontal stria arched 

 and complete, scape of the antenna angulatc on the outer 

 edge, niesosternum marginate and sinuous anteriorly ; anterior 

 tibiiu vvitjj tarsal groove straight, not curved. The super- 

 tieies of the species is similar to a small Plutysoma^ but the 

 tarsal grooves agree better with those of Pkeliater. The very 

 fine surface punctuation is almost identical in the two species 

 known and is an exceptional character. Tiie two species to 

 be included in the genus are Flatysoma exortivain^ Lew. 

 (1888), and socialis, described below. 



Chronus socialis, sp. n, 



Ovatus, parum dopressus, undique tenuis.sime punctulatus ; fronto 

 subplana, stria Integra antice late arcuata ; pronoto stria latcrali 

 basi vix abbreviata, interstitio modice dilato ; elytris striis 1-3 

 integris, 3 iuternus subaequalibus ; propjgidio i)ygidio(iue sat 

 dense punctulatis hoc immarginato ; mesosterno sinuate mar- 

 ginato ; libiis auticis u-deuticiiiatis. 



L. 3A mill. 



CH-al, somewhat depressed, black and shining, surface 

 above and below microscopically punctulate; the head not 

 impressed, frontal stria well marked and widely arched ; the 

 thorax, marginal stria very tine, inner stria obscurely crenu- 

 late and tine behind the head, stronger and not crenulate at 

 the sides, and the interstice a little widened, the stria is very 

 slightly shortened at the base (in exortivus it just passes the 

 angle) ; the elytra, dorsal striaj 1-3 complete, suluial dimi- 

 diate, -4-5 a little shorter and almost coequal ; the pygidia 

 are not margined but rather closely punctulate, the points 

 somewhat varying in size ; the niesosternum is sinuous and 

 the stria complete ; the anterior tibiie 5-dentatc, tarsal grooves 

 not curved. 



This species is very similar to e.vortivus, but the frontal 

 stria is more marked, the thoracic lateral interstice is wider 

 and the striu does not reach the basal edge, and of the three
