226 NEW SPECIES MELYRIDAE, CHRYSOMELIDAE AND TENEBRIONIDAE 



muricate laterally and on the apical declivity ; humeri rather distinct ; disk 

 moderately convex to somewhat flattened at times. 



Otherwise as in scabricula. 



Male. Elongate oval and narrower. 



Female. More robust. 



Measurements. Length (Types), 20-21 mm.; width, 9-10 mm. 



Holotype, male, and allotype, female, in my own collection. Para- 

 types in that of Mr. Ralph Hopping. 



Type locality. Cannel Meadow, Kern County, California ; col- 

 lected June 11, 1913, by Mr. Ralph Hopping. 



Habitat. Cannel Meadow and Breckenridge Mountain, Kern 

 County, California. A paratype from the latter locality was taken at an 

 altitude of 6000 feet. Number of specimens studied, nine. 



Acutangula differs from scabricula in its distinct and quite strong 

 apical pronotal angles, coarser sculpturing and more opaque lustre. In 

 scabricula the apical angles are distinctly obtuse and rather narrowly 

 rounded, basal angles obtuse and not in the least prominent. In 

 acutangula the basal angles are distinct and obtuse, and rendered slightly 

 prominent by the basal bead alone. 



A single specimen taken by Mr. J. R. Slevin, at Glenbrook, Nevada, 

 on August 25, 1913, is referred to this species. 



Tenebrio tenebroides Beauv. This phase or race of T. picipes 

 Herbst., according to the Leng Catalogue of the Coleoptera of North 

 America, has a wide range of distribution, being particularly mentioned 

 as occurring in Southern California, Newfoundland and Florida. In all 

 probability it is only one of the modifications of the cosmopolitan picipes. 



Some thirty years ago I took a single specimen from beneath the bark 

 of a tree on top of the Bolcan Mountain, near Julian, San Diego County, 

 California. This region was isolated as far as commerce was concerned, 

 but not far distant from the Santa Isabel Indian Reservation. At any 

 rate the specimen remained a unique in my collection until quite recently, 

 when Mr. F. W. Nunenmacher found another in Shasta County, and 

 meanwhile Mr. Ralph Hopping collected another at Fort Tejon, California. 

 All these localities were away from commercial warehouses. These 

 specimens differ from the eastern examples in being more distinctly 

 punctured on the upper surface. In the more abundant specimens of 

 picipes Herbst. the punctuation of the head, pronotum and elytral intervals 

 is scarcely distinct. In both forms the punctures of the elytral striae are 

 distinct. The manner of dispersion of cosmopolitan species is an inter- 

 esting problem. 



Helops simulator, new species. Form elongate-ovate, alate; wings 

 about as long as the elytra ; densely punctate above. Color black.
