Mar. 1899] Fall : On American Species of Acm^^odera. 23 



Habitat: Colorado, Utah, California (desert regions), Oregon 

 (Hood River). 

 A. ornata Fab., Syst. Ent., p. 220. 



This common and widespread species is too well known to need 

 any comment. 



Habitat: Pennsylvania, Florida, Texas, Utah, Nevada. 



37. A. rubronotata Lap. e^" Gory, Mon., I, p. 5, t. i, f. 5. 



According to the authors of the Biologia, the above name should 

 be used for the species now standing on our list as j-/<?/Arr/j- Chev., 

 which is believed to be quite a different thing. SteUaris Spin., is 

 doubtfully placed as a synonym of rubronotata. This species is easily 

 recognizable by Horn's description and figure. I have seen only the 

 two examples in the Leconte collection. Length, 11. 5 mm., .46 

 .inch. 



Habitat : Texas, along the Mexican border. 

 A. van dykei, sp. nov. 



Form broad, depressed, color piceous with faint bronze lustre, clothed above with 

 fine erect fuscous hairs ; elytra maculate with small orange red spots which have a 

 tendency to coalesce into four or five broken transverse bands, none of which reach 

 the suture. Head with distinct vertical carina. Thora.x more thali twice as wide as 

 long, widest a little before the base, sides strongly narrowed in front, margin more or 

 less distinctly visible throughout from above ; surface rather closely, moderately 

 coarsely punctate, impressed as usual. Elytra a little narrower than the thorax, sub- 

 triangular, strise moderately punctate, more coarsely at sides as usual ; intervals flat 

 on the disk, the third at base and the fifth to a greater extent more or less elevated. 

 Body beneath bronzed, prosternum emarginate in front, abdomenusually sparsely finely 

 punctate though somewhat variable ; last ventral without trace of apical plate. 

 Length, 9-12 mm., .36-.48 inch. 



Habitat : Ten examples from Washington, California (Siskiyou, 

 Alameda and Los Angeles Counties), Nevada and Utah — Collections 

 of Van Dyke, Fuchs, Horn and Wickham. 



I take pleasure in dedicating this species to my friend Dr. Edwin 

 C. Van Dyke, whose collection of Californian Acmceodera is the most 

 extensive I have seen and has in its entirety been very kindly placed 

 at my disposal. 

 A. prorsa, sp. nov. 



Moderately robust, subtriangular, depressed, shining, bronzed, hairs of upper 

 surface fine, moderately long and dark brown in color ; of the under surface grayish 

 white elytra marked with a series of four more or less transverse lateral yellow spots, 

 that nearest the humerus small and often wanting. Head closely punctate, feebly 

 impressed at middle, vertical carina indistinct. Thorax a little wider than the elytra,
