Grenus—APROSTOMA. Guérin-Méneville. 
(Guérin-Méneville, Rey. Zool. 1839, p. 171.) 
The type of this genus inhabits Madagascar, and was, in 1842, in the Collections of Messrs. Reiche and 
Guérin-Méneville, the latter of whom, in 1842, allowed me to make a careful figure of it, and who considered it 
to be allied to Calodromus among the Brenthide, and to Colydium. The former relationship is due only to the 
very elongate and slender form of the insect. The latter is its genuine affinity, as is proved by the structure of 
the different parts of the mouth.
