NEW SPECIKS OF NORTH AMERICAN HYDNOCERA 



(COLEOPTERA). 



BY A. B. WOLCOTT, INDIANAPOLIS, IND. 



The author has had in preparation a monograpli of the genus 

 Hydnocera, it being now evident that the results can not be pubh'shed for 

 some litlle time, and specimens having been sent out bearing MS. names, 

 it is thought advisable to make known some of the most conspicuous 

 forms among the new species, 



Hydnocera ccertcleipeiinis, n. sp. — General form of pallipennis^ but 

 more elongate and shining. Dark bluish-green, elytra bright blue-green ; 

 antennas, palpi, all the tibi?e and front and middle tarsi pale testaceous, 

 the two basal joints and club of antennae, apices of palpi, labrum and 

 posterior tarsi piceous, the front and middle tarsi slightly infuscate, all the 

 green parts with metallic lustre. Antennae short, moderately slender, mass 

 acuminate at apex. Head with the large prominent eyes much wider 

 than the thorax, very finely and densely rugulose, front densely clothed 

 with short slivery white recumbent and long erect grayish hairs, a 

 conspicuous bunch of long erect grayish hairs below the eyes. Thorax as 

 long as broad, apical constriction strong, sides before the middle rather 

 strongly dilatated, sides posteriorly nearly straight, strongly convergent, 

 apical and basal transverse impressions strong, disc coarsely, densely but 

 not very deeply punctate, slightly rugulose at sides, lateral foveas large, 

 deep, pubescence rather sparse, long, erect, gray. Scutellum densely 

 clothed with semirecumbent grayish pubescence. Elytra covering the 

 abdomen, scarcely wider at base than the head, twice as long as wide at 

 base, humeri moderately prominent, sides straight, moderately narrowing 

 to apex, apices separately rounded and dehiscent at suture, sides behind 

 the middle and apices strongly serrate, pubescence rather sparse, gray, 

 erect and semierect at base, becoming shorter, more dense and erect and 

 recumbent toward the apices, very coarsely, deeply and slightly confluently 

 punctate, punctures not smaller at apex and but slightly more confluent. 

 Legs long, slender, posterior femora not nearly attaining the apex of 

 elytra, clothed with long erect cinereous hairs. Meso- and metasternum 

 densely clothed with short silvery white recumbent pubescence ; abdomen 

 more sparsely, with longer white hairs. Length, 3.75 mm. 



Santa Rita ]\Its., Arizona, 5,000-8,000 feet. July. F. H. Snow. 

 This beautiful species is very distinct from all the known species of 

 our fauna, the form of the prothorax agreeing very nearly \v'\\\\ pallipennis
