538 On the Genus Hapaloclirus, Er. 



Bourgeois, Gorliam, and Pic, who Jo not allude to them in 

 their descriptions of Hapalochrus. This oversight is, of 

 course, due to Kraatz having placed his insects under a new 

 genus — Hadrocnemus , — which is based upon the extraordinary 

 development of the anterior and intermediate tibipe in the 

 males, about which Erichson says nothing in his generic 

 diagnosis, though he mentions this character in the description 

 of H. azureus, and it is also to be found in his H, festivus, of 

 which he only knew the female, the type being the Eastern 

 JI. (^Malacldus) Icetus, F. The name Hadrocnemus, applicable 

 as it is, is not really required, there being a complete tran- 

 sition in the development of the tibiae of the male from the 

 species in which they are greatly swollen and eroded (//. sum- 

 tuosiis, Boh., &c.) to those in which they are simple, as in the 

 female. 



Tiie synonymy of the eight African species enumerated by 

 Kraatz will stand as follows: — 



1. Hadrocnemus conradti, Kr. ( J" ? ) (pp. 60, 271), from 



Bisniarckburg, Togo-^ Hapalochrus mahchioides, Fairm. 

 (1887). Quoted in my paper (sp. no. 16) as " H. con- 

 radti. Pic, in litt. (■?)," in the synonymy of //. malacld- 

 oides. 



2. Hadrocnemus coeruleus, Kr. (J ?) (p. 60), no locality 



given, but presumably from Togo, may or may not be 

 synonymous with the common and widely-spread W.- 

 African Hapalochrus azureus^ Er. {=^cceruleusj Murr., 

 1867) (No. 38 of my paper). Tiie specific name, in any 

 case, is preoccupied for an insect absolutely congeneric. 

 Kraatz's specimens (length i^i-i^ mm.) appear to be a 

 little larger than any of those referred by me to //. azu- 

 reus ; he describes the ^ as having " femoribus tibiisque 

 anticis intermediis testaceis, dilatatis, his extus nigris," 

 and the elytra as nude in S ^^'^ shortly pilose in ? ! 



3. Hadrocnemus srnkcB, Kr. (cJ ? ) (p> 61), from Mombasa. 



Not recognizable in the material examined by me. The 

 length is given as 3 lin., presumably in error for 3 mill., 

 as the insect is said to be small and the measurements of 

 the other species are given in millimetres. 



4. Hadrocnemus imrpuripennis, K.Y. (^'^) (p. 61), from Bis- 



niarckburg, belongs to Heterolaius, Champ, (tinte^ 

 pp. 178,179), as shown by the elongate subequal second 

 and third joints of the antennai in ? . It is doubtless 

 synonymous with Hapalochrus [Lai'us) inflaticornisy 

 Fairm. (type S > 1894, from the Congo) and H. (Luius) 

 violacei colli s, Pic (1907). This latter name was incor- 

 rectly given by me as violaceipeniiis (ante, p. 17^).
