Description of a new Genus and four new Species of 



North American Cleridae. 



BY A. B. WOLCOTT, Chicago, 111. 



The few species here made known have been carefully 

 chosen, the object in view being to select only such species as 

 are very distinct from their nearest allies, hence no confusion 

 should arise as a result of describing them at this time. 



Cymatodera cognata sp. nov. 



Piceous, subopaque, antennae and an irregular, obscure median fas- 

 cia rufo-piceous, sparsely pubescent. Head densely confluently and 

 rather coarsely punctate ; eyes feebly prominent. Antennae slightly 

 longer than head and thorax, joints two to ten subequal, slender, 

 eleventh a little longer. Thorax nearly one-half longer than wide, 

 moderately constricted in front of middle, strongly compressed at 

 sides behind, base narrower than apex, surface moderately coarsely 

 but not very densely punctate, ante-scutellar impression distinct, limit- 

 ed each side by a prominent tubercle. Elytra nearly twice as wide as 

 base of thorax, hunieri distinct, sides slightly divergent posteriorly, 

 apices conjointly rounded, disk with striae of moderately fine punctures, 

 those of the sutural striae extending scarcely to middle, the lateral 

 striae much longer, an obscure, irregular fascia at middle scarcely at- 

 tains the suture. Body beneath finely and sparsely punctate, abdomen 

 and legs subrugose. Length 8-9.5 rnm. 



Male. Fifth ventral segment feebly emarginate, longitudinally 

 carinate at middle from base to apex ; sixth oval, feebly emarginate ; 

 last dorsal oval, shorter and narrower than the corresponding ventral, 

 subtruncate at apex. 



Female. Fifth ventral broadly, feebly emarginate, feebly carinate 

 at middle ; sixth oval, incised at apex ; last dorsal elongate oval, broadly 

 triangularly emarginate at apex. 



Las Vegas, Nevada (type $ ) ; Stockton, Utah (type 9). 

 Both specimens were collected by Mr. Tom Spaulding, and 

 were sent me by Mr. Warren Knaus, to whom my thanks are 

 due for one of the types. 



This species is of the form of inornata, but less slender, and 

 with elytral sculpture nearly as in fuscula. It is nearest allied 

 to the species of the belfragci group (belfragei, morosa, flavo- 

 signata and umbrina), from all of which it differs in second- 

 ary sexual characters of the abdomen and in other details,
