PIIYLLOBIINI. 107 



third, striatc, striae finely and closely punctured, intervals flat, densely 

 scaly and with minute sub-erect hairs. Body beneath densely scaly and in 

 color similar to the upper surface. Legs piceous or piceo-rufous, femora 

 densely scaly, tibiae paler and more distinctly pubescent. Length .20-. 28 

 inch ; 5-7 mm. 



The color of the scales is very variable and may be rather brilliant green, 

 slightly cupreous, plumbeous or cinereous. Usually the sides of the elytra 

 are paler than the rest of the surface, the suture always so. 



Occurs from Canada to California. 



S. californicus, n. sp. 



Form of elegansr but slightly narrower. Surface less densely covered 

 with brownish or ferruginous piliform scales, the region of the suture 

 irregularly marmorate with white. Thorax scaly, broader than long. 

 Legs pale rufous, sparsely pubescent. Tibiae very feebly arcuate. Length 

 .24 inch ; 6 mm. 



These few words give the differences observable between the two 

 species. The head is also narrower, and the rostrum less robust. 8. call 

 fornicus resembles the mustela of Europe. 



Two specimens, Eldorado Co., California. 



MITOSTYLUS n. g. 



Rostrum cylindrical, shorter than the head, slightly narrower, tip very 

 feebly emarginate, and with a smooth triangular space. Scrobes short, 

 badly defined, suddenly flexed. Eyes longitudinally oval, slightly trun- 

 cate in front. Antennae slender, three-fourths the length of the entire body; 

 scape long, slender, slightly clavate and attaining the margin of the thorax; 

 funicle 7-jointed, 1-2 longer, the first longer than the second ; 3-7 obconical, 

 gradually shorter ; club elongate, oval, pointed at tip. Thorax cylindrical, 

 sides feebly arcuate. Scutellum small, triangular. Elytra not wider at base 

 than the thorax, oblong oval. Metasternum rather short. Intercoxal pro- 

 cess broadly oval, second segment longer than the two following, first 

 suture arcuate at middle. Tibiae straight, tarsi slender, claws connate. 

 Tenth elytral stria free in its entire extent. Body densely scaly. 



The gular notch is rhomboidal, the mentum narrow, an extremely 

 feeble peduncle, maxillae distinctly visible, and the labial palpi rather 

 prominent. This insect resembles the figures of Eusomus ovulum. 



M. tenuis, n. sp. 



Form rather slender, surface densely covered with bluish white scales. 

 Head and rostrum longer than the thorax, sparsely punctured, moderately 

 densely scaly. Thorax cylindrical, as wide as long, sides feebly arcuate, 

 apex slightly obliquely, base squarely truncate and slightly narrower than 

 the apex, disc moderately convex and scaly, sparsely punctured. Elytra 

 oblong oval, striate, striae moderately closely punctured, intervals flat, 

 densely scaly and with minute, erect, whitish hairs. Body beneath densely 

 scaly. Legs rufous, femora darker and sparsely scaly, tibiae pubescent. 

 Length .12-. 14 inch ; 3-3.5 mm.
