Jan son believes that, although indicated as coming from Bengal, 

 his example is a native of South Africa, owing to its close affinity to 

 S. bicolor, Westw. 



Gen. SMARAGDESTHES, Kraatz, 

 Entomol. Monatsbl., ii., 1880, p. 28. 

 — Isandtila, Thorns., Cat. ii., p. 410. 



The former genus was published some six months before the 

 second, but in the same year. 



Gen. PACHNODA, Burm., Cat. ii., p. 434. 



Pachnoda albonotata, Mos., 

 Ann. Soc. Ent. Belg., Ii., 1907, p. 314. 



" Black, shiny, marked with white. Head strongly punctate, cly- 

 peus sub-quadrate, anterior edge emarginate ; prothorax, with the 

 exception of a narrow median line, coarsely punctate, anterior margin 

 slightly produced in the middle, and having a narrow lateral white 

 line abbreviated behind ; scutellum sparsely punctate, obtuse at 

 apex; elytra sub-serrately punctate, and having on each side twelve 

 small, white macules ; pygidium sparsely aciculate punctate, and 

 bi-maculated with white. Underside fulvo-pilose laterally ; the 

 mesosternal process is small, semi-orbicular, and not directed down- 

 wards ; abdomen of the $ sulcate. Anterior tibiae bi-dentate. 



Length 19 mm. 



Hab. German South- West Africa." 



In size, shape, and coloration this species resembles much 

 JRhabdotis albinigra, Burm., but owing to the shape of the meta- 

 sternal process it cannot be included in this genus. 



Pachnoda rufovirens, Qued., Cat. ii., p. 440. 



It would seem that this species is the true P. discolor, Koib., 

 Cat. ii., p. 440. 



Pachnoda marginella, Fabric, Cat. ii., p. 439. 



Read var. eup>arypha, Gerst. Arch. f. natur., xxxvii., 1871, i., p. 46, 

 line 34, instead of cuneata, &c. 



Kraatz himself has admitted P. euyarypha to be a variety of 

 P. marginella. The outer characteristics are not sufficiently distinct 

 to differentiate between the two with any degree of precision. But 

 there is a slight difference on the genitalia of euparyplia. I regret, 

 however, that I have been able to examine one $ only, and this 

 difference may prove not to be constant.
