prothorax has not been observed by me in any other 

 species. S. reversa seems most nearly allied to S. mar- 

 ginata. 



39. Hyperaspis excelsa, sp. nov. 



Broadly oval, strongly convex; shining, rather finely punctate; black, 

 elytra with humeral marginal stripe joining a large transverse discal spot, 

 red; a smaller apical spot sometimes present. Male with head, sides of 

 thorax narrowly, front margin still more narrowly, and front legs, yellow. 



Length, 3.75 mm. 



Southern California (Pomona, Pasadena, San Ber- 

 nardino Mountains); rare. 



Marked much like H. tceniata, but very much larger 

 and with somewhat different sexual color marks in the 

 male. 



40. Hyperaspis spiculinota, sp. nov. 



Elongate-oval, subdepressed; shining, except the head, which is finely 

 reticulate and somewhat dull; black, with the sides of the thorax, median 

 and apical marginal, and elongate discal spot, yellow. Legs dull yellowish, 

 the femora more or less piceous. Head yellow in the male. 



Pasadena and Pomona; not common. 



The markings of this species are of the H. undulata 

 type, but the humeral spot is never present, and the 

 discal spot is very narrow, elongate, subtriangular, 

 pointed behind, and truncate in front. The marginal 

 spots are rather narrowly separated but are not con- 

 nected in any specimens which I have seen. The 

 oblong, depressed form, and shape of discal spot are 

 characteristic. 



There are in my cabinet three or four other probably 

 undescribed species from Southern California, but they 

 are not sufficiently strongly characterized, or not pres- 

 ent in sufficient numbers, to warrant their description 

 in advance of a monographic treatment of the genus.
