the pronotum, by the mesothoracic epimera prolonged externally, and 

 by the condition of the tarsi, which may be considered as intermediate 

 between those of Anclioinenus and Colpodes. 



Blackbubnia, Sharp. 



The curious insect for which I proposed this generic name, is a 



very distinct genus : there is no pronotal seta ; the basal margin of 



the elytra is very peculiar, being towards the middle sloped backwards, 



the scutellum is quite small, nearly concealed, and the mesothoracic 



epimera are a good deal prolonged externally. These characters are 



supplementary to those I mentioned when describing the genus 



originally. 



DiSEKOCHus, Blackb. 



This genus was correctly referred by Mr. Blackburn to the An- 

 chomenini, and Karsch was in error in treating the species known to 

 him as a Pro7necoderus, which is a genus of Broscini. The mistake of 

 the German savant was, however, a pardonable one, as 'Disenochus has 

 much the appearance and characters of the Broscini, the mesothorax 

 being pedunculate or sub-pedunculate, %nd the elytra unmargined at 

 the base, and the scutellum placed entirely on the mesothoracic |>eduncle. 

 There are two systematic setae on the pronotum, one in front of the 

 middle and one a little in front of the hind margin ; the two orbital 

 setse occupy the usual positions. 



Ateachtcnemis, Blackb. 



This represents another most interesting insect, which I have 

 been able to study only by a single example, which was deprived of 

 tarsi, antennae and palpi on its journey to me. Though located by 

 both Blackburn and Karsch in the Harpalidce, yet its true relationship 

 is, I believe, with the Hawaiian aberrant Anchomenini. There are two 

 orbital setae, the posterior being placed far from the eye, owing to the 

 reduction of the magnitude of this organ. The pronotal setae I can- 

 not speak of, owing to the condition of my specimen, but probably 

 there is a single one (which, like those of the head, maybe very feeble) 

 near the hind angle ; the elytra, though possessing rather prominent 

 shoulders, are not margined at the base, and the scutellum is placed 

 entirely on the thoracic peduncle ; the elytra are remarkably free 

 from sinuation behind, and closely adapted to the hind-body. These 

 characters are (since the importance of the orbital setae in the classi- 

 fication of the CarahidcB has been demonstrated) consistent only with 

 the location of their possessor in the Anchomenini, though it must be 

 admitted that the general facies is an approximation (but only an 

 approximation) to that of the Dapti group of the sub-family Harpalini.
