1917] Insects in Burmese Amber 325 



Burmese amber; from Mr. R. C. J. Swinhoe. In the same 

 slab as the type of Acmaeodera burmitina, and about 8 mm. from 

 it. It is named after Professor Wickham, who has done so 

 much to elucidate the fossil Coleoptera, and gave me valuable 

 advice concerning this specimen. I at first took this insect 

 for a new genus of Oedemeridae, not noticing the short but 

 evident neck.* It may go in Eury genius as interpreted in 

 the broader sense, though it may hereafter be treated as the 

 type of a distinct genus. It quite closely resembles E. fragili- 

 cornis Champion from the Seychelles, differing however by 

 . the prominent mandibles, relatively slender last joint of palpus, 

 more globose thorax and sculpture of elytra. When Casey 

 discussed the Eurygeniinae- (Eurygeniini, Casey) in 1895, he 

 remarked that they were wholly confined to the new world. 

 Since that time the genus has been found scattered over the 

 eastern hemisphere, E. niponicus Lewis coming from Japan, 

 E. africanus Kolbe and E. nigricolor Pic from the African 

 continent, E. hovanus and E. griseopubens of Fairmaire, from 

 Madagascar, E. abdominalis Pic from Bengal, and E. fragili- 

 cornis and E. convexicollis of Champion from the Seychelles. 

 Reitter recognized a Pedilus in Baltic amber*. 



Elater (sens, latiss.) burmitinus sp. n. (Elaterid^). 



Length about 11 mm., elytra 7.7 mm.; narrow, width at base of 

 elytra about 3 mm.; thorax finely punctured, the posterior comers 

 sharp, obliquely truncate (see Figure); el^^ra finely hairy, obtuse at 

 apex, surface with eight simple parallel striae, between which are numer- 

 ous very minute piliferous punctures. The color is uniform black. 



Burmese amber, from Mr. R. C. J. Swinhoe. Certainly 

 not a species of the true genus Elater, but I am unable to refer 

 it to a modern genus with any assurance, the under side and 

 appendages being invisible. It is in a slab, 8 mm. from the type 

 of Hodotermes tristis. 



*Say described a member of this group as Oedemera vestita.
