Not obtained by the Percy Sladen Trust Expedition. The Catalogues of Lewis 
and Bickhardt, referred to above, are followed in placing punuilio Er. as a synonym 
of quattuordecimstriata Steph. Lewis gives as the distribution ‘‘ Cosmopolitan” ; while 
Bickhardt gives South and West Europe, and North America.

All three of the species found in the Seychelles belong to this subgenus: that 
is to say, they have no sutural stria on the elytra, and the keel of the prosternum 
has definite strize on either side and is not narrowed in front of the coxz (see Lewis, 
Opmcits ps sls, tie) 4):

Paromalus alluaudi Schmidt, Bull. Soc. ent. France, 1893, p. 100; Alluaud, Liste

1 ¢ and 1 9, determined by comparison with Schmidt’s actual type ¢ and ? and 
with another typical pair, all sent by Monsieur Alluaud. I have closely compared 
upper and under surfaces of both sexes side by side; the ? obtained by me has the 
prosternal strize a little wider apart, but in all other respects, including the remarkable 
sculpture, it agrees with the specimens received from Alluaud: the ¢ agrees closely. 
Schmidt states that this species has the facies of certain Indian species, and is 
very closely allied to Paromalus mendicus Lewis from Japan and Java. 
Loc. Seychelles. Silhouette: forest above Mare aux Cochons, well over 1000 feet, 
IX. 1908, 1 g and 19. La Digue, in numbers under bark, 1892 (Alluaud).
