seven to nine increasing rather rapidly in width, ninth and tenth strongly' 

 transverse, equal, a little longer than the third, together scarcely as long as the 

 eloventli, which is ovoidal and pointed. Frothorax widest at one-third its 

 length from the apex, where it is very slightly narrower than loug; sides 

 thence vmy strongly convergent and broadly sinuate to the apex which is 

 slightly produced, truncate at tip and less than one-third as wide as the disk; 

 sides in the posterior two-thirds rather rapidly convergent to the base and 

 very feebly arcuate; apical angles obtuse, rather narrowly rounded and 

 somewhat prominent; b.isil rather broadly rounded; disk feebly convex, 

 feebly and broadly ridged along the middle especially in the basal half 

 where it is broadlj' and feebly biimpressed. Elytra at base distinctly wider 

 than the prouotuui; sides very feebly divergent, feebly arcuate; together 

 broadly, angularly and feebly emargiuate behind; disk quadrate, subde- 

 pressed, very slightly longer than the pronotum, coarsely and very closely 

 granulate; on each elytron (here is a very feeble impression extending from 

 the scutellum slightly obliquely and near the suture nearly to the apex. 

 Scutellum very indistinct, small, roundeil. Abdomeii at base as wide as the 

 elytra, and, at the apex of the lirst segment, slightly wider; sides gradually 

 convergent and slightly arcuate to the apex; border strongly inclined and 

 very distinct; surface moderately convex, coarsely and densely ruguloso- 

 granulate. Under surface of the head coarsely and closely punctate; 

 punctures round, variolate and almost in contact; under surface of the 

 abilomen shining, rather finely punctate; punctures asperate and arranged 

 in wavy, interrupted, transverse rows. Length 1.7-2,0 mm. 



Texas; (Galveston t2). 



Tlio scul]ituro of tlu^ pvoiiotum consists of a very minute 

 reticulation of coarse strongly elevated lines. 



The sexual cliaracters are very feeble; the type is a male 

 and lias tlie aj^ex of the sixth segment broadly truncate or 

 excessively feebly sinuate throughout; in the female the 

 sixth segment is longer and extremely feebly angulate 

 throughout its width at a])ex. The male is much smaller 

 than tlie female. 



The two representatives of this very interesting species 

 were found in detritus and rubbish on tlie inner side of the 

 sand dunes lining the ocean beach. It is the smallest 

 Pa3deride described from the United States.
