A REVISION OF NORTH AMERICAN CHRYSOBOTHRINE 211 



on each side ; with median lobe strongly produced and narrowly truncate in front 

 of scutellum; disk uneven, slightly convex, flattened at middle, with a narrow, 

 smooth, longitudinal, median line, numerous small, irregular, smooth callosities 

 toward sides, a large, irregular callosity on each side near front, and another 

 opposite middle of base of each elytron ; surface densely, finely, irregularly punc- 

 tate in depressions, punctures coarser and deeper toward sides. Scutellum short, 

 triangular. 



Elytra distinctly wider than pronotum, one and three-fourths times as long as 

 wide, widest at humeral angles, which are broadly rounded; sides converging 

 from humeral angles (more strongly on apical halves) to tips, which are con- 

 jointly broadly rounded ; lateral margins slightly serrate ; basal depressions broad 

 and moderately deep ; humeral depressions broad, shallow, and irregular ; surface 

 glabrous, uneven, depressed areas finely, densely, irregularly punctate. Bach 

 elytron with four more or less distinct, smooth, longitudinal costae ; first narrow, 

 extending from apex to base; second and third forming large, irregular, smooth 

 callosities, some of which are connected to first costa ; fourth costa narrow, irregu- 

 lar, following outline of lateral margin. 



Abdomen beneath sparsely, coarsely, irregularly fossulate-punctate, sparsely 

 clothed with short, recumbent, white hairs, with large, slightly elevated, smooth, 

 lateral callosities, intervals nearly smooth ; basal sternite broadly, longitudinally 

 sulcate at middle ; last visible sternite broadly, sinuately truncate at apex, with 

 angles slightly produced, longitudinally carinate at middle, with a slightly ser- 

 rate, submarginal ridge, lateral margins not serrate ; eighth tergite densely punc- 

 tate, broadly rounded at apex. Prosternum nearly smooth at middle, coarsely 

 punctate and transversely rugose at sides a'nd along anterior margin, sparsely 

 clothed with rather short, recumbent, white hairs ; anterior margin without a dis- 

 tinct median lobe. Anterior femur with a short, acutely triangular tooth, which 

 is not distinctly dentate on outer margin. Anterior tibia slightly arcuate, 

 unarmed at apex; middle and posterior tibiae straight. 



Length 22 mm., width 10 mm. 



Male. — Unknown. 



Redescribed from the female holotype, No. 3446, in the Academy of 

 Natural Sciences of Philadelphia. 

 Type locality. — "Arizona." 



DISTRIBUTION 



From material examined : 



Arizona: No definite locality, type (F. G. Schaupp), Huachuca Mountains, May 

 (United States National Museum. This is the specimen listed by Chamberlin 

 (1926) as being in the Academy of Natural Sciences of Philadelphia). Jose- 

 phine Saddle, Upper Madera Canyon, Santa Rita Mountains, 7,000 feet 

 elevation, September 25, 1924 (Mason collection). 



Also recorded by Chamberlin (1926) from Senator, Ariz., June 1, 

 in the Leng Collection. 



Host.— Chamberlin (1926) lists it from Arizona white oak (Querem 

 arizonica Sargent), but this host record should be verified, as it may 

 refer to the Packard (1890) record for chlorocephala, erroneously 

 listed by Chamberlin under chalcophoroides. 



This species seems to be rare in collections, and the writer has ex- 

 amined only three specimens, all of which are females. The sculpture 

 is rather peculiar for a Chrysobothris, as it resembles more closely 

 that of some species of the genus Chdlcophora. No variation worthy of 

 mention was observed in the specimens examined.
