REVISION OF ELEODIINI— BLAISDELL. 501 



dentate angle has a small seta at middle of its side toward the 

 emargination; contiguous sides of the processes of each adjoining 

 segment narrowly chitinous, very minutely and irregularly denticu- 

 late ; posterior third of the process of first segment not develoi^ed ; 

 processes of seventh segment imperfectly developed. Anal cerci with 

 a few scattered setse. 



Pronotum with a lateral marginal row of comparatively closely 

 and evenly spaced chitinous seta\ internal to whicli is a submarginal 

 series of distantly spaced seta\ often broken otf and appearing as 

 minute chitinous tubercles; there is also a ])ost-apical series of very 

 distantly spaced and similar setie, as well as an antebasal series simi- 

 larly spaced. 



In Plate 13, fig. 2, it will be seen that the post-apical series appear 

 as marginal when viewed from above. 



On the dorsal surface of the head there are four to six seta^ ; dor- 

 sal surface of abdominal segments three, four, five, and six with a 

 seta each side near basal and external angle. Legs with a short seta 

 on outer anterior femoral region near the knee; fourth ventral ab- 

 dominal segment with a subapical row of seta\ 



Tribe BLAPTIN^I. 



In (BJaps) the globular outer antennal joints, wide epipleurse 

 which terminate upon the external surface of the cauda when present, 

 the intercoxal tubercle of the first abdominal segment and the pubes- 

 cent pit at base of the second abdominal segment the present tribe 

 stands in marked contrast to anything observed in the genus Eleodes, 

 and in fact all of the genera of the Eleodiini, except in the wide 

 epipleura? which forms the whole inflexed sides of the elytra in 

 Eleodbnorpha. 



The genital characters are certainly very distinct and more primi- 

 tive than is to be seen anywhere in the Eleodilni. 



Genital characters^ male. — Lobes of the sternite strongly connate, 

 clavse connate, lying dorsad to and forming a i^allium for the edeagus, 

 more obsolete alw, more embryonic condition of the edeagophore, 

 there being a complete solution of continuity in the chitinization 

 along the median line of both the basale and apicale, these segments 

 being longitudinally subdivided by an evident membranous line into 

 lateral sclerites. 



Female. — Valves of the genital segment (Plate 5, figs. IG and 17) 

 completely chitinized. apex of each undifferentiated, appendage ab- 

 sent. The facies of the segment is quite different from that observed 

 in the Eleodlini^ but a phylogenetic relationship is evident. 



I am not desirous to repeat what may alreadv be known in Europe, 

 but simply to indicate my reasons for not retaining the genus Blaps 

 in the same tribe with the others dealt with in this paper.
