table they would not be associated with alpicola, but with 

 hi color, from which they are structurally very different. 



Automolus depressus, Blanch. 

 This species varies from a form having the clothing of 

 the pronotum entirely pale to one in which it is entirely black. 



Automolus granulatus, Blackb. 



The enormous propygidium of this species, in comparison 

 with the small pygidium, and the dark club readily distinguish 

 this species from all others of the genus except hinnilis and 

 propygidialis. The type and only specimen known to Black- 

 burn was evidently a male; the female differs in being more 

 or less castaneous (the head, scutellum, and pygidium ex- 

 cepted), and each elytron with a conspicuous postero-lateral 

 glabrous space (much larger than on the female of humUis).

Automolus burmeisteri, Macl. 



In Blackburn's table of the species of Automolus this 

 species (with others) is distinguished by "pilosity of pronotum 

 dark at least in middle of disc." This is generallv true of the 

 males, but all of the numerous females before me have the 

 pilosity entirely of a rusty red, and even on some males black 

 hairs are not always present (19) , although generally con- 

 spicuous on the middle. The sexual brand on each elytron of 

 the female is smaller than usual (about the length of the 

 scutellum, but only about half its width). 



Automolus semitifer, Blackb. 



Of this species Blackburn had four females under examin- 

 ation, and of these there are now three before me, all of 

 which have the club black. The co-types are slightly greasy. 

 but specimens in better condition have a curious silken or 

 pruinoee gloss on the pygidium, propygidium, and abdomen, 

 very conspicuous from some directions; in consequence the 

 punctures, although shallow, appear considerably larger than 

 they otherwise would, and the hairs with which they are 

 supplied project in a curious way. The sexual brand on the 

 co-types is continuous on each elytron, from the shoulder to 

 the apex, but on some others it is interrupted in the middle, 

 so that each appears to have two smaller ones, one on the 



(19) It is difficult to distinguish such males from males of 

 depressus, apart from the shorter pilosity of the pygidium and 

 propygidium.
