538 On the Genus Hapaloclirus, Er. 



Bourgeois, Gorham, and Pic, who do not allude to them In 

 their descriptions of Hapaloclirus. This oversight is, of 

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

 genus — Hadrocnemus, — which is based upon the extraordinary- 

 development of the anterior and intermediate tibife 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 

 II. (Malachius) 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 (H. sum- 

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

 female. 



The synonymy of the eight African species enumerated by 

 Kraatz will stand as follows : — 



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



Bismarckburg, T ogo — Hapaloclirus makichioides, Fairm. 

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

 radti, Pic, in litt. ('?)," in the synonymy of II. malachi- 

 oides. 



2. Hadrocnemus coerulens, 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 Hapaloclirus azureus, Er. (=^cceruleun } Murr., 

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

 case, is preoccupied for an insect absolutely congeneric. 

 Kraatz's specimens (length 'l^-lf 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 $ ana " shortly pilose in ? ! 



3. Hadrocnemus sr niece, Kv. (^ $ ) (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. 

 1. Hadrocnemus purpuripennis, Kr. ( $ ) (p. 61), from Bis- 

 marckburg, belongs to Heterolaius, Champ, (ante, 

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

 and third joints of the antenna? in $ . It is doubtless 

 synonymous with Hapaloclirus (Lat'us) inflaticornis, 

 Fairm. (type <$ , 1894, from the Congo) and //. (Laius) 

 violaceieoUis, Pic (1907). This latter name was incor- 

 rectly given by me as violaceipennis {ante, p. 179).
