COLEOPTERA OF BAJA CALIFORNIA. 363 



but similarly pubescent, fimbriate at apex. Abdomen 

 above sub-opaque, finely but not densely punctate, each 

 segment with a double series of oblong velvety spots ; 

 beneath more shining and more sparsely punctate. Legs 

 black. Length, .55 inch. ; 14 mm. 



The male has the last ventral truncate and vaguely 

 emarginate. This species belongs to the division Platy- 

 dracus Thoms., which Dr. Sharp does not admit as of 

 full generic value. In form the above described species 

 resembles nlgrellus, but differs in the form of the head 

 and the presence of velvety spots on the abdomen. From 

 the arrangement of our native species suggested by me 

 (Trans. Am. Ent. Soc. vii, p. 186) hicaniis will be found 

 most closely related to toiucnlosits, but the latter is more 

 robust and has no smooth median thoracic line. 



Occurs at La Chuparosa. 



SCAPHISOMA PENINSULARE n. Sp. 



Form of terniiiiatnni but smaller, piceous black shin- 

 ing, elytra narrowly paler at apex, legs and two basal 

 joints of antennse pale. Head and thorax smooth. Elytra 

 relatively coarsely, sparsely punctate, the punctures less 

 distinct at base, sutural striae curved outward at base, 

 one-third toward humeri. Body beneath smooth. Length, 

 .04 inch ; i mm. 



This species is evidently reflated to desertorwn Casey, 

 but is smaller and with more coarsely punctured elytra 

 and a shorter basal extension of the sutural stria. 



Sierra Laguna. 



SCAPHISOMA APICALE U. Sp. 



Form of convexmn. Body beneath rufo-testaceous, 

 legs paler, head and thorax slightly darker, elytra piceous 

 broadly tipped with rufo-testaceous. Head smooth, 

 thorax microscopically punctulate. Antenna? pale, the
