only slightly more than one-third of their width; antennse slender, filiform, 

 not at all incrassate, one-half as long as the body, the last joint mnch thicker, 

 swollen at the middle, obliquely pointed and distinctly longer than the two 

 preceding. Prothorax distinctly narroAver than the head, only slightly wider 

 than long, parallel and straight at the sides, broadly arcuate at apex, faintly 

 impressed along the median line toward base and apex, strongly and rather 

 closely punctured. Scutellum large, broadly triangular, narrowly truncate at 

 tip. Elytra one-half longer than wide, about twice as wide as the prothorax, 

 parallel and feebly arcuate at the sides, gradually narrowed and not very 

 broadly rounded in apical third; disk broadly, very feebly impressed within 

 the humeri, the impression traceable obliquely for some distance from the 

 base; punctures strong but \\'ell separated. Length 2.1 mm.; width 0.8 mm. 



District of Columbia. Hubbard and Schwarz. 



The single t3'pe is a male having the slender apex of the o3deagus 

 protruded, but the sexual characters are not very pronounced, the 

 fourth ventral being perfectly simple, unmodified on the disk and 

 only slightly longer than the third, the hind femora moderately 

 inflated. It is probable that the female has the last joint of the 

 antennffi less sw^ollen and distorted. 



5. Z. scliwarzi n. sp. — Resembles the preceding, but differs in its 

 broader form and shorter elytra. Head transverse, the eyes large; antennje 

 moderately thick and of tlie usual length. Prothorax transversely subquad- 

 rate, strongly punctate. Elytra scarcely two-fifths longer than wide, parallel 

 and just visibly arcuate at the sides, narrowed in apical third, the apex rather 

 narrowly rounded; intra-humeral impression extending obliquely and quite 

 distinctly almost to the middle; punctures somewhat coarse, moderately close, 

 becoming toward finer apex. Length 2.2 mm. ; width 0.9 mm. 



Florida ( Biscay ne Bay ). Hubbard and Schwarz. 



The under surface is dark brownish-rufous throughout, the 

 elytra paler, rufo-testaceous, with a transverse median fascia of 

 black which is more than one-third as wide as the total length, 

 broadly produced posteriorly along the suture for a short dis- 

 tance ; each elytron also has a small black spot at the middle of 

 the base; the legs are black, the femora picescent at base, the 

 tibise paler toward base and apex, and the tarsi pale. The pubes- 

 cence is long and distinct. 



This species is represented in my cabinet by a single male ex- 

 ample.
