ing spots as in the variety described below. Intergrades how- 

 ever exist which link them all together. 



The species so far as I know is confined to California, 

 though widely distributed there as well as uncommon. I have 

 seen one specimen from the Sierra Madre Mountains of Los 

 Angeles County, collected July 6, 1912, by J. C. Bridwell and 

 now in the collection of the Division of Entomology, Univer- 

 sity of California ; five from near Placerville, including speci- 

 mens collected by H. E. Burke, F. H. Herbert, and the type, 

 one from Hullville, Lake County, collected by L. R. Reynolds, 

 and three from Los Gatos, collected by F. H. Herbert. The 

 material secured by Mr. Burke and Mr. Herbert was taken on 

 Ceanotlms cuneatus Nutt. 



Type in my own collection, collected above Placerville along 

 the Placerville road, El Dorado County, June 9, 1906, by F. W. 

 Nunenmacher and by him kindly presented to me. 



Acmaeodera sinuata sex-notata n. subsp. (PI. VII, fig. 3). 



Like typical form except proportionately broader and with the lat- 

 eral yellow band broken up into large spots. These are situated, one 

 just posterior to the humeri, a second at about the middle of the sides, 

 and a third between that and apex with a trace of a fourth slightly 

 posterior to the last. The three large soots are all somewhat trans- 

 verse, extending from the margin of the elytra inwards to almost the 

 second stria in the case of the first, almost to the third stria in the 

 second, and to the third in the third. Length 9.5 mm., breadth 4 mm. 



This variety superficially resembles in size, shape and mark- 

 ings typical forms of A. robtista Horn. It can however readily 

 be distinguished from that by lacking the yellow spots of the 

 thorax as well as by its more bronzed elytra and less sinuate 

 anterior margin to prosternum. While all the specimens in the 

 lot from which the type was taken are broad, others have been 

 seen which were of the exact shape of typical sinuata. These 

 were also taken in company with the latter. I have seen four 

 specimens of the broad form in the collection of Dr. F. E. 

 Blaisdell and know that Mr. L. R. Reynolds also possesses 

 some six or eight taken at the same time and place as the type 

 and from Ceanofhus cuneatus Nutt . and two specimens of the 

 narrower phase in the collection of Mr. H. E. Burke, both
