200 APOGONIA BASIVENTRIS. 



NOTE XXL 



APOGONIA BASIVENTRIS, N. SP. 



DESCRIBKD BY 



C. RITSEMA Cz. 



Very closely allied to and much resembling A. ventralis 

 Moser ') from Tonkin and of the same length (9.5 — 10 mm.) 

 but proportionately broader and less parallel. Both species 

 have the base of the abdomen (the two basal ventral seg- 

 ments) and the apex of the elytra dull black, the anterior 

 tibiae tridentate and the sides of the abdomen not sharply 

 margined. 



The new species is distinguished from ventralis: 1° by 

 the broader and less parallel shape of the body ; 2° by the 

 punctuation of the pronotum, the punctures being some- 

 what larger and slightly more distant from one another; 

 3° by the space between the humeral costa and the first 

 of the two lateral interstices, which space is broader be- 

 hind the shoulders tlian it is in ventraUs] 4° by the more 

 conspicuous very minute erect white setae, visible with 

 the aid of a strong lens, in the punctures on the elytra of 

 basiventris, which setae are almost imperceptible in ventralis. 



Apogonia basiventris comes from Theinzeik in Burma 

 (R. F. Loizeau) and is represented in the collection of 

 Mr. René Oberthür and in the Leyden Museum. 



Obs. After the name Apocjonia Moseri was proposed by 

 me ^) in behalf of A. lobata Kolbe (non Ritsema), Mr. von 

 Dalla Torre ^) bestowed the name meruana upon this 

 African species. The name Moseri ought to be maintained, 

 being for several months earlier in date of publication 

 (resp. April and December 1912).
