428 AMERICAN PACHYBRACHYS (cOLEOPTERA) 



Elytra confusedly punctate along the suture and in a narrow basal triangle, 

 stria generally traceable and somewhat impressed, four to six more or less 

 confused anteriorly; marginal interspace rather narrow, impunctate, except 

 about the subbasal dislocation of the eighth stria; shield distinct but not large; 

 spots small, sharply limited, those of the outer series marginal, the posterior 

 spot transverse but not confluent with the corresponding inner one; anterior 

 and middle spots of the inner series often elongate, the posterior one confluent 

 with the dark sutural stripe. 



Pygidium yellow, with base and median cuspiform stripe fuscous. Body 

 beneath brown or fuscous, sides and apex of venter more or less pale. Legs 

 yellow, the middle and hind thighs whitish yellow in outer two-thirds, brownish 

 at base; tibiae with brownish rings or shades in apical third. 



Length 2.1 to 2.7 mm.; width 1.1 to 1.4 mm. 



Distribution.— Florida: Tampa, March and April (Hubbard and Schwarz); 

 Enterprise (Griffith), (Schacffer). 



Suffrian gives no more definite locality than the "Eastern Region." 



I have used for this species the name borne by a specimen in 

 the LeConte Collection. Judging from description it seems 

 likely to be the real thing, but of this I am not sure. It is very 

 closely allied to varians, which is perhaps no more than a varietal 

 form of the present species. 



108. Pachybrachys osceola new species 



Yellow with brown punctures and standard spots, head very 

 unevenly punctate, eyes separated in the males by a distance only 

 slightly greater than the vertical width of their upper lobes; 

 front without ocular lines; elytra! striae deep, front claws of 

 male not enlarged. Ave. length 2.5 mm. Florida. 



Head closely rather coarsely punctate in the brown vertex spot and impressed 

 median line, otherwise sparsely so. Eyes separated in the male by very 

 slightly less, and in the female by a little more, than twice the length of the 

 basal antennal joint. Antennae yellow, outer joints in part brown, three- 

 fourths as long as the body in the male, tenth joint barely three times as long 

 as wide. 



Frothorax widest a little in front of the base, sides moderately rounded at 

 this point, moderately convergent and feebly arcuate or nearly straight an- 

 teriorly; punctures sparse in the pale areas, dense in the RI, which in the male 

 type is rather small and broken, in the female sonKnvhat l)roadly suffused; 

 side margins nearly free from punctures. 



Elytra irregularly punctate in a small baso-sutural triangle, the striae quite 

 deeply impressed and entire, except five and six, which are confused before the 

 middle, eight strongly sinuous and with a subbasal interruption; marginal 

 interspace impunctate, shield rather large, subtriangular; standard spots 

 fairly distinct.
