Malticoderm Genera Prionccerus and Idgia. 333 



pxtremcly large, almost contiguous ; labrum transverse, 

 subtrapczoidal, moderately large ; apical joint of maxillary 

 palpi long, cultriform ; antennae moderately long, joints 

 4-10 gradually increasing in width and decreasing in length, 

 10 longer than broad, 11 about the length of 9 and 10 

 united, curved, hollowed on its inner face. Prothorax 

 longer than broad, very uneven, rugulosely punctate. 

 Elytra long, rounded at the tip ; densely, rugulosely 

 punctate. Anterior tarsal joints 1-3 with a narrow black 

 comb on their inner edge. Genital armature (PI. XI. fig. 5j: 

 lateral lobes broad, short ; median lobe drawn out into a 

 very long, slender, strongly curved point. 



Lengtii (excl. head) 9, breadth 3 mm. 



Hab. \y. Africa, Senegal (Mus. Brit.). 



A male in the Museum, labelled " Epiphyta melannra, Dj., 

 Senegal," agrees with the brief diagnosis of /. terminata. 

 Cast., from that locality, and a longer description is given from 

 the specimen before me. It is separable from /. longipalpis 

 by the smaller labrum, the shorter, less dilated antennae, 

 and the wholly testaceous prothorax. /. abyssinica has a 

 much larger labrum, a smaller head, a n;irrower apical 

 patch, &c. Tiie similarly-coloured Prionocerus senegalensis, 

 Cast., under which E. melanura, Dej., is placed as a synonym 

 in the * Munich Catalogue,' should have the antennie serrate 

 as in the type-species of that genus. 



4. Idgia apicalis. 



Prionocerus {Idgia) apicalis, Gerst. Arch, fiir Naturg. xxxvii. p. 56 

 (1871) ; Von der Decteu's Reise in Ost-Af rika, iii. 2, p. 169 (1873). 



^ . Eyes very large, subapproximate above and beneath ; 

 anterior tarsal joints 1-3 with a black comb along their 

 inner edge, 4 small, narrow. Genital armature : lateral 

 lobes long, broad ; median lobe narrow, acuminate, some- 

 what hooked at the tip. 



Bab. E, Africa, Mombasa and Zanzibar. 



A male from Zanzibar, received by the Museum in 1868, 

 is certainly referable to tliis species. A narrow, elongate, 

 ochraceous insect, with the head (except in front), and a 

 small patch at the tip of the elytra, black; the antennae long, 

 subfiliform ; the body thickly pubescent, the head with 

 numerous long dark bristly hairs, and the elytra sparsely, 

 seriately nigro-setose; the apical joint of the maxillary 

 palpi long, subcultriform j the labrum transverse, subquad- 

 rate. The genital armature has not been dissected, but it is 

 partly extruded in the single specimen before me.
