indication of a second (very short) on the disk. The punctuation is closer and stronger 

 than in A. hopfneri, especially a little way below the shoulders. 



10. Actenodes reichei. (Tab. II. fig. 18.) 



Actenodes reichei, Thomson, Typi Buprestid. 1878, p. 74. 



Hob. Mexico \ Playa Vicente, Santecomapan, Tuxtla (Salle), Oaxaca (Brit. Mus.) ; 

 Guatemala, Chacoj (Champion); Nicakagua, Chontales (Janson). 



This species is described as " obscure viridi-metallica ; elytra obscure brunneo-metallica, 

 maculis 10, et lineis 2 obliquis posticalibus mridi-cwpreis, ornata. Long. 16-17 mill." 

 M. Thomson gives the species as A. reichei, Laferte, MSS., stating that it is near to, but 

 very distinct from, "A. desmarestii, Gory." 



In the British-Museum collection there are specimens with the label "reichei, Laf.," 

 named from Laferte's collection, and therefore no doubt identical with M. Thomson's 

 species. The description omits to mention that the ten spots are in reality frosted 

 impressions, and their position is not stated ; there are two on each elytron close to the 

 base, subconfluent, two some way before the middle (one near the suture and the other 

 on the margin), and a single one in the middle of the elytron, rather behind the middle. 



I know of no such species as "A. desmarestii, Gory." 



11. Actenodes sallaei. 



Actenodes sallei, Thomson, Typi Buprestid. 1878, p. 73. 

 Hob. Mexico. 



I only know this species from description, of which the following is an extract : — 

 " Obscure metallica ; elytra sutura marginibusque cuprea. Scutellum viride. Elytra 

 pone suturam costis 2 longitudinalibus obsoletis instructa, lateribus posticis nee denti- 

 culata, apice biacuta. Tarsi obscure cyanei. Long. 13 mill." 



CHALCANGIUM, n. gen. 



General form and characters of Chrysobothris. Eyes widely separated ahove. Antennal fossa moderately 

 large, shallow, and round. Prosternal process only slightly angular on each side immediately behind the 

 anterior coxa?. The metasternum not emarginate in front. Anterior femora simple, not dentate. Tarsi 

 very slender ; the third joint with its apical angles produced into two slender spur-like processes, as in 

 Actenodes, but in a less degree, and not diverging ; the fourth joint very small (not produced into a lamina 

 below), almost hidden in the third joint. Abdomen with a fine median raised line on the second to fifth 

 segments. Thorax narrower than the elytra, the posterior angles fitting close to the elytra. Scutellum 

 small, elongate, triangular. 



The species for which I propose this new genus has somewhat the appearance of 

 Chrysobothris costifrons, but is more elongate and has no impressions on the elytra. 

 The almost simple form of the prosternal process, the unarmed anterior femora, and 

 the peculiar structure of the tarsi necessitate the creation of a new genus for its 

 reception.
