58 AMERICAN COLEOPTERA. 



" Black, clothed with large oval scales of a light and dark brown color; pro- 

 thorax with a large subquadrate spot of white scales at the hind angles, elytra 

 with white spots as follows: a small dot at the base of the sixth interspace; a 

 transverse spot on the second and third interspaces, one-foui'th from the base; 

 immediately behind this spot a large dark space ; a smaller transverse spot behind 

 the middle; a large lateral spot opposite the first ventral segment, and an adjoin- 

 ing small spot on the seventh interspace; the apical edge is also clothed with 

 whitish scales." Interocular space narrowest at middle, where it is about two- 

 fifths the width of the eyes. Second joint of funicle slightly longer than the 

 first. Length 3-4 mm.; width slightly less than half the length. 



"Southern California" (type) ; Ensenada and San Felipe, Lower 

 California; Yuma, California; Tucson, Arizona (Schwarz) ; Nueces, 

 Texas (Marlatt), San Antonio, Texas (Soltau). The Lower Cali- 

 fornia specimens are nearly typical ; those from Yuma, Tucson and 

 Texas are more obscurely marked and perhaps represent a closely 

 allied but distinct species. 



The small pale spot described by LeConte as on the seventh inter- 

 space is really on the eighth, and it, as well as the posterior trans- 

 verse spot on the second and third interspaces, is a little elevated. 



C priiiceps u. sp. — Robust, clothed with intermixed white and pale brown 

 scales, the former predominating, giving the insect a cinereous aspect. The 

 brown scales predominate on the posterior portion of the thoracic disk and in a 

 transverse posteriorly arcuate spot at the middle of each elytron, attaining the 

 sutural interspace and limited somewhat obscurely both before and behind by 

 narrow pale bands. Anterior transverse row of prominences fairly distinct and 

 coincident with the pale margin of the central spot; posterior series of promi- 

 nences ill defined or obsolete. Beak coarsely punctured from base to apex, the 

 punctures moderately dense at sides, sparser along the median line above; an- 

 tennal funicle moderately, the fifth tarsal joint densely, albosquamose. Inter- 

 ocular space unusually wide, narrowest distinctly above the middle of the eye, 

 where it varies from two-fifths to rather more than one-half the ocular width ; 

 inner margin of the eyes scarcely diverging superiorly. Length 5.5 6.1 mm.; 

 width 2.7-3 mm. 



Three examples of this fine species are before me ; two taken by 

 Mr. Coquillet in " Los Angeles Co., Cal." and now in the National 

 Museum collection, and a third given me by Mr. Albright who col- 

 lected it in Santa Monica Canon ( also in Los Angeles County). 



The largest of our species, and distinct from all others l)y the 

 squamose antennal funicle and fifth tarsal joint. 



C littoralis u. sp. — Moderately elongate, suboval, white above and be- 

 neath, a dark spot each side of the middle at the base of the prothorax, a subtri- 

 aiigular sutural spot of brownish scales at the middle of the elytra. Beak stout 

 and coarsely rather closely punctured, except along the median line; interocular 

 space narrowest just above the middle of the eye, where it is nearly or quite
