In discussing this paper Mr. Walton recounted having once 

 observed a species of Sphex in New Mexico attempting to dig a 

 hole in the bottom of a galvanized iron wash-tub. 



ONE NEW GENUS AND TWO NEW SPECIES OF CERAMBYCIDyE. 



BY W. S. FISHER, Branch of Forest Insects, Bureau of Entomology. 



In working over the Cerambycidse received from the field men 

 of the branch of forest insects, Bureau of Entomology, during 

 the past year, the following apparently new species were en- 

 countered. For one of these, a species from California, the larva 

 of which bores in pine cones, it was found necessary to erect a 

 new genus. 



All types and specimens mentioned are deposited in the United 

 States National Museum in Washington. 



Hylotrupes juniperi n. sp. 



Male: Elongate, rather robust, subdepressed, shining black. Antennae 

 three-fourths as long as the body. Thorax rounded on the sides, suddenly 

 narrowed towards the base, w r hich is slightly tubulate, the sides are densely 

 and confluently punctured, the disc with three smooth longitudinal eleva- 

 tions, one median reaching from base to middle, and a crescent shaped 

 one on each side forming a somewhat broken circle. Elytra each with 

 two indistinct lines, surface very densely punctured, the punctures larger 

 and less dense on the basal half, and becoming very small towards the 

 apex, sparsely clothed with short black recumbent hairs. Femora not 

 clavate. Fifth ventral segment truncate behind. Length 22 mm.; width 

 6 mm.

 as long as the body, and the fifth ventral segment broadly rounded behind. 

 Length 25 mm.; width 7 mm. 



Habitat: Santa Catalina Mountains, Arizona. Elevation 4200 

 to 5000 feet. W. D. Edmonston and M. Chrisman, collectors. 



Type and allotype: Cat. No. 19129 U. S. N. M. 



Described from seven specimens. Two males and two females 

 recorded under Bureau of Entomology Number Hopk. U. S. 

 12698. Material collected December 1, 1914, by W. D. Edmon- 

 ston, from heartwood of green limb on dying Juniper (Jinri/ierus 

 pachyphloca) . One male and two females recorded under Bureau 

 of Entomology Number Hopk. U. S. 12259c, and reared from 

 material collected by M. Chrisman on November 18, 1913, in 

 the same locality from dying Juniper. Larva always makes 

 burrows with the grain of the wood, half in the bark and half
