basiil impressions deej), triaii>;ular, reaeliiiig nearly to middle. Elytra scarcely 

 wider at base than the thorax, humeri obliquely rounded, unibone not prominent, 

 disc with ten entire stria; of moderately coarse punctures, closely placed, but not 

 serrate, the outer stria distant from the margiji, a short scutellar stria of but few 

 punctures, intervals broader than the strife, smooth. Body beneath brown, the 

 abdomen almost smooth. Legs rufotestaceous, the hind femora darker. Length 

 .08 inch. ; 2 mm. 



The only sexual difference apparent in the specimens before me 

 is in the broader first joint of the anterior tarsus of the male. 



Specimens occur with the apical pale space quite sharply limited, 

 while others have been seen in which the elytra are almost entirely 

 piceous. 



Occurs from Massachusetts (Blanchard) to Florida and Texas. 

 I have seen one in the LeConte cabinet from California. 



Group XII.--EUPLECTBOSCELES. 



Antenme 11-jointed. Anterior coxal cavities closed behind. Tho- 

 rax with a faint ante-basal impressed line. Middle and posterior 

 tibiee sinuate near the apex, the posterior grooved their entire length. 

 Tarsal claws divaricate, not appendiculate. Ventral segments all 

 free. 



This group is suggested for the genus Euplectroscelis Crotch, which 

 that author had associated with Chsetocnema. From the group c(m- 

 taining the latter it differs in the free ventral segments, the presence 

 of a feeble ante-basal impression, the irregularly punctate elytra 

 and the simple claws. The (Jiily other tribe to which the key of 

 Chapuis directs is the Oxygonites, from which the form of the tibi?e 

 and claws at once separates it. 



As I'emarked by Crotch the facies of the only species known is 

 rather that of a Eumolpide than a Halticide.

Head inserted in the thorax as far as the eyes, front not carinate, 

 the tubercles distinct and widely separated, clypeus arcuate in front. 

 Labrum transverse, slightly emarginate at apex. Maxillary palpi 

 slender, second joint elongate conical, third cylindrical, fourth acutely 

 oval, longer than the preceding and not narrower at base than it. 

 xVntennaj slender, a little longer than half the body, first joint elon-
