NEW COLEOPTERA FROM THE SOUTH-WEST.— II. 



BY H. C. FALL, I'ASADKNA, CALIFORNIA. 



The new species in the writer's collection selected for description in 

 the following pages are representatives of the genera Cymatodera and 

 Hydnocera, of the Cleridse, and have been now chosen in order that their 

 publication may be as nearly conteinporaneous as possible with the recent 

 descriptions of new species by Mr. Schaeffer and Dr. Skinner, whose 

 articles have aroused some present interest in this family. 



Cymatodera delicatula, n. sp. — Very small, similar in most respects 

 to piindicoUis. Brown, antennae and legs uniformly rufotestaceous, front 

 of head, apical and basal margins of prothorax and apex of elytra gradually 

 paler ; elytra with a broad, antemedian yellowish transverse fascia, which 

 is not at all narrowed at the suture. Antennae stout, nearly half the length 

 of the body, joints 2-4 subequal and smaller than those following, outer 

 joints subcylindrical, gradually wider apically, but not at all triangular; 

 last joint longer, obtusely pointed. Eyes very prominent, especially in 

 the ^ , in which they are separated on the front by a distance scarcely 

 greater than their own vertical diameter. Head and prothorax very 

 minutely sparsely punctate, the latter much wider at apex than at base ; 

 basal c(tnstriction strong, apical constriction moderate, width at middle 

 subequal to that at apex. Elytra at base nearly twice as wide as the base 

 of the prothorax, humeri rectangular, sides slightly diverging posteriorly, 

 striae consisting of quite coarse perforate pimctures, which become finer 

 at apex ; intervals as wide as the punctures near the suture, becoming 

 narrower at sides ; each with a row of fine distant punctures ; pubescence 

 fine, rather long, suberect, the alternate interspaces with widely-spaced, 

 longer, somewhat stouter^ erect hairs, which are most conspicuous on the 

 third. 



Length, 3.2-4.2 mm. 



]\Iale. — Fifth ventral with posterior margin scarcely visibly emarginate; 

 the sixth broadly feebly arcuato-emarginate from side to side ; last dorsal 

 rounded and feebly notched. 



Female. — As in pinidicollis. 



Described from a single pair sent me by Mr. Beyer, by whom they 

 were taken at Santa Rosa, Lower California. This species is closely 

 related to piincticollis, but ap[)ears to be distinct in its somewhat less 

 coarsely punctate elytral striae, broader, complete transverse fascia, colour
