times as long as the greatest width. Eyes wanting, two speci- 

 mens on a sUde in balsam showing pigmented lateral spots which 

 may represent eye facets. Ocelli wanting. 



Thorax well developed; pronotum from dorsal view about as 

 long as broad, about as long as the meso- and metathorax com- 

 bined, and very broadly rounded anteriorly and truncate posterior- 

 ly the sides very gently rounded and gradually convergent pos- 

 teriorly where it is nearly a fourth narrower than anteriorly, the 

 length about equal to the anterior width; mesonotum from above 

 half as long as the pronotum and posteriorly broadly rounded, the 

 sides straight and gradually divergent posteriorly, where the width 

 is slightly greater than that of the posterior part of the pronotum ; 

 metanotum similar to the mesonotum in length and shape but a 

 little broader. 



Legs stout, coxae very large and broad, being fully as broad 

 as the femora; trochanters well developed, being of about the 

 thickness of the apical tarsal segment and a little longer than 

 broad; femora stout and decidedly swollen, about four times as 

 long as broad and beset with small bristles except on the inner 

 surface, which is naked, otherwise unarmed except the posterior 

 ones; on the inferior caudal margin of which there are two black 

 chitinized teeth, one at the basal and apical thirds; the hind 

 femora are somewhat larger than the others and have eight or 

 nine bristles on the lower margin in addition to the two larger 

 chitinized teeth ; tibia less than one-half as thick as their respective 

 femora and of about the same length except the posterior ones, 

 which are somewhat longer than the corresponding femora; the 

 tibiae are beset on every side by short bristles but are otherwise 

 unarmed; the anterior ones on the anterior inferior margin with a 

 series of a score or more bristles; tarsi consisting of two segments, 

 the basal one triangular and very minute, the second one large, 

 somewhat less thick than the tibiae, about five or six times as long 

 as broad and beset all over with short bristles which, like those on 

 the tibiae and femora, are not erect but considerably inclined. 

 Claws two in number on each foot, slender, as long as the thick- 

 ness of the terminal tarsal segment and abruptly curved at a 

 right angle at about the basal fourth. 



Abdomen but little flattened, from a dorsal view decidedly
