TRIARMOCERUS Hichh. 
21. Triarmocerus, sp.? 
As stated above, the absence of the antennze in the single specimen before me, 
prevents any trustworthy determination ; the tibize are similar to the generic description, 
as given by Eichhoff, although the specimen does not agree in other points with either of 
his described species. 
Loc. Coetivy, 24. TX. 1905. 
Dryocares Eichh. 
22. Dryocetes furvus, sp. n. 
Oblongus, subfuscus, piceo-niger, antennis pedibusque testaceis ; prothorace oblongo- 
ovali anterius rugulis transversis exasperato, posterius rugulose punctato, elytris ad 
apicem oblique declivibus, lineato-punctatis, interstitiis post medium uniseriatim pilis 
erectis obtusis ornatis. 
Long. 2°25 mm. 
Differing from D. nubilus Blandf. in being slightly narrower, the prothorax rather 
less rounded basally and the median smooth line less distinct ; the setze more obtuse and 
the general colour of the insect less shiny. 
Loc. Seychelles. Silhouette: from near Mont Pot-d-eau, ca. 1500 feet, VIII. 1908,
