the Seyclitllcs Inlands and Ahlihra. 183 



several examples were obtained by Mr. Scott in the same 

 island in x. and xi. 1908 near Mornc Hlanc, not in the highest 

 forcsrs, but between 5fX) and lOUO (cet. A few were collected 

 at Long and Round l^,lands, small cultivated islets off Port 

 Victoria, Malie, vii. 1908, Several were also found in 

 Felicite and Marie Anne Islands, xii. 1908, in a rather dry 

 type of forest near sea-level. 



Kolbe's description was made from a single example, and, 

 as the antennal structnie is not mentioned by him, it is not 

 quite certain whether the name should be applied to this or 

 the loilowing species. The first ridge on the posterior tibise 

 and first tarsal joint is at most feebly developed and often 

 wanting. Amongst the series examined there are at least 

 two of each sex with the genital organs extruded, so that 

 theie can be no mistake as to their identification. 



21. Mordellistena degressa, sp. n. 



Exti-emely like M. jnahena, but differing from it in having 

 the antennae le.-s elongate in both sexes (in ^ about as long 

 as ill $ of M. mahe?ui), comparatively short and suhserrate 

 in ?, joints 3 and 4 small and equal in length in the two 

 sexes, 5 twice as long as 4, 5-11 moderately elongate iu (^ . 

 Posterior tibiae and tarsi as in M. ma/tena. 



Length (incl. pygid.) 3j-4|^ mm. (c? ? .) 



Loc. Seychelles : Mahe, Silhouette. 



Nine specimens, eight of which are from Mahe. All are 

 from the mountain-forests. These appear at first sight to 

 be females of M. mahena ; but as there is no corres[)ouding 

 variation in the develoj)ment of the antennte in the long 

 series of the allied forms from the Seychelles, the examples 

 ■with a short fourth joint must be separated from the rest. 

 M. deyressa, therefore, is based u[;on examples with seven, 

 and M. mahena with eight, elongated antennal joints. 



22. Mordellistena parlilis, sp. n. 



^ . Rather short, narrow, convex ; black, the head, an- 

 tenme, mouth-parts, prothorax, anterior and intermediate 

 legs, and the posterior tibife and tarsi in part, testaceous ; 

 the elytra variegated with cinereous and black pubescence, 

 the latter condensed into a very large tiausverse patch at 

 the base (not quite reaching the suture) and a common, 

 broad, postmedian fascia (leaving a sharply defined sub- 

 median and apical fascia cinereous), the vestiture of the 

 pygidium and under surface cinereous, that of the head and
