13. Synfcophoderes g-ixineensis, Kolbe ( 1895).

14. Nessiabrissus r* ufi tar-sis, Jord. (1895).

 1901 and III. 1902; Basile, VIII-IX. 1901; Punta Frailes, X-XI.

15. Xylinad.es thomasius, Jord (1911V 



S. Thome, one &.: Agua-Izé, 400-700 m. ■ XII. 1900. 



I described the species from a 9 . The present tf , which is 

 the first I have seen, agrees with the 9 except in the special tf 

 - characters. The tenth antennal segment and the apex of the 

 ninth bear long wool on the inner side,, the eighth having a 

 smaller, apical, tuft; the relative lengths of these three segments 

 are 18, 6, 15, the third segment measuring 21. 



16. Xylinades princeps, nov. spec. 



cf 9- Color et statura X. thomasii, sed distinctius nigro-ma- 

 culatus, antennarum articulo 10.° nigro, clava c? glabra. 



Hab: Principe, a series of both sexes: Roca Inf. D. Henrique, 

 II, III, IV and V. 1901. 



• The black markings are more sharply defined than in X. tho- 

 masius, forming spots and dots, of which a rounded median 

 spot on each elytrum is the largest and most prominent, cover- 

 ing two and a half or three interspaces. Alternate interspaces 

 dotted with black. 



Whereas in X. thomasius the tenth antennal segment has 

 the same silky grey pubescence as the eleventh, in princeps 

 the tenth is pubescent brownish black. The club, in the cf , has 

 no wool on the inner surface, and the proportional lengths -of the 

 segments are different, the segments measuring respectively 13, 

 6, 14 in the larger tf tf and 11, o, 12 in the smallest one.
