196 ZOOLOGICAL EESULTS OF THE EUWENZOEI EXPEDITION. 



Family Trogositid^. 



Alindria guakdis Serv. Encycl. Meth. x. 1825, p. 719. 



Fort Belli, Semliki Valley. This is common from the Gold Coast to Natal. 



Family E r o T T L i D ^. 



Promecolanguria cuprea Arrow, Johnston's Uganda Ir'rotectorate, vol. i. p. 460 

 (1902). 



Between Salt Lake and Wawamba, S.E. Ruwenzori. 



Keddish-brown, head nearly black, elytra with a metallic lustre ; parallel-sided, 

 elongate, head finely and not closely punctured, thorax rather densely, elytra with 

 deeply impressed rows of punctures. Antennae with a loosely three-jointed club, the 

 two preceding joints very slightly widened. Eyes moderately finely facetted. Prothorax 

 rather longer than wide, with the sides hardly perceptibly curved and slightly 

 approximating behind. Elytra truncate at the extreme apex. Length 12 mm. 



This species is allied to P. lyctoides Fowler, but is considerably larger than that 

 or any other described species of the genus. Three specimens were found by 

 Mr. Scott Elliot. 



PliATTDACNE RUFOVITTATA Harold. 

 Megalodacne rufovittata Har. Col. Hefte, xvi. 1879, p. 219. 



Mubuku Valley, E. Ruwenzori, 6000-13,000 ft. 



Two specimens were found, which agree with the description of Harold's examples 

 from the interior of Angola, except that the third joint of the antennae is as long as, 

 but not, as stated by Harold, longer than the fourth and fifth together. The prothorax 

 is not quite so long as it is broad, but its unusual length produces that impression. 

 The three red lines upon each elytron are less reduced than in the original type and 

 each is broken into two parts, but the degree of constancy of these lines cannot yet 

 be judged. 



This species, although much more elongate, is very closely related to JPlatydacne 

 vittulata, Fairm., and must unquestionably be placed in Fairmaire's genus, notwith- 

 standing that that author has indicated the shortness of the prothorax as one of its 

 characteristics. 



Amblyscelis nigripennis, sp. n. 



Fulvo-rufus, elytris clavaque antennali nigris ; modice elongatus, minute punctulatus, 



elytris punctato-striatis, parum nitidis, oculis baud magnis. 

 Long. 6-7 mm. Lat. max. 3"3 mm. 

 Ilab. Euwenzori, 5300 ft.; Belgian Congo, Katanga; N.E. Ehodesia, Serenje.
