first segment, there is a tliin transverse erect lamina, gradually curved back- 

 ward, the apex appearing immediately under the middle of the emargination 

 of the first segment ; from the posterior base of the erect lamina there projects 

 obliquely backward a small straight narrow ligula. Remainder of abdomen 

 simple. Legs rather slender, the posterior tibise bent, the intermediate shorter 

 and thicker. Length 1.25 mm. ; width 0.65 mm. 



New York. 



The abdominal characters of this species are more nearly homo- 

 logous with those of the texana group than with ahdominalis or 

 intermedia. It is one of the smallest species of the genus. 



In the desert regions extending from western Texas to southern 

 California there are species of a peculiar type, pale ferruginous in 

 color and having the first dorsal segment in the male very long, in 

 fact constituting the entire abdomen when viewed from above, with 

 the apex deflexed and more or less broadly sinuate in the middle. 

 I have before me three species, all represented by the male alone, 

 the female being apparently very rare ; they may be distinguished 

 as follows : — 



Elytra but slightly wider than long, the suture vqyj much longer than the 

 first ventral segment, with the sides less divergent and more arcuate. 

 First dorsal segment with the sides subparallel, at the apex much wider 

 than the elytra at the humeri ; second nearly twice as long as the third, 

 the apex broadly, feebly sinuate in middle fourth, the surface feebly and 

 approximately biimpressed in median fourth and anterior half; second 

 and third segments strongly punctate throughout ; third and fourth sub- 

 equal in length ; last dorsal broader, even, entire and very broadly 

 rounded at apex. Length 1,5 mm, ; width 0.7 mm. Southern California. 



loripes n. sp. 

 First dorsal strongly narrowed from base to apex, at the latter point scarcely 

 wider than the elytra at the humeri ; second transverse at apex, scarcely 

 at all longer than the third, feebly, obliquely impressed on the disk at 

 each side of median third in anterior half, and also along the apical 

 margin, the central portion between the impressions very feebly elevated, 

 strongly punctate and setose ; third segment one-half longer than the 

 fourth, with the apex broadly and very feebly sinuate in the middle ; 

 last dorsal with a short beveled spongiose apical region, the anterior 

 margin of which is abruptly limited and broadly anteriorly arcuate 

 throughout the width ; body otherwise nearly similar in form and size to 



loripes though rather less stout texaiia. Csy. 



Elytra short and transverse, the sides strongly divergent from the humeri and 

 nearly straight ; suture but slightly longer than the first dorsal ; second 

 dorsal scarcely more than one-half as long as the third, deeply emarginate 

 in the middle of its anterior margin under the apex of the first, the surface 

 with a transverse elevated median tubercle occupying the entire segmental
