however, prefer to put it with Dineutus s. str., as the large 
size and the highly developed anterior legs of the males show 
more affinity with the representatives of the latter subgenus. 
Hatch, among many other erroneous suppositions, in his 
publications on the Gyrinidse, adds in the same paper the 
statement that spinous elytral apexes are a character en- 
tirely lacking in Dineutus s. str. He overlooks the fact that 
in several species from the Madagascar and the Ethiopian 
region we meet with such a condition, so the spinose elytral 
apex does not exclude D. longimanus from the subgenus 
Dineutus s. str. Moreover, in D. truncatus Sharp from 
Central America, we can recognize the truncature of D. 
longimanus in a moderate form. A profemoral tooth, the 
presence of which is denied by Hatch for the species, is 
weakly intimated in large males of D. longimanus. 
Gyretes vulneratus Aube 
Of this species, which hitherto was represented only by a 
few specimens in old collections (i.a. Mus. Berlin, Bremen, 
Senckenberg; types in coll. Dejean), the Cambridge Museum 
possesses a considerable series, all from Haiti. The speci- 
mens in a series from Furcy (W. M. Mann) agree rather well 
with the ancient ones seen by me, which are perhaps from 
the same region as Aube’s types. All females are very 
strongly reticulate on the disc of pronotum and elytra, and 
on the sides of the latter there are two abbreviate ridges 
with a short longitudinal depression between them. 
Gyretes vulneratus, forma 9 laevicollis forma nov. 
In several series taken in Haiti by Mr. Darlington, most of 
the females have the disc of pronotum and elytra smooth 
(reticulation very fine) as in the males, and on the sides of 
elytra there is no noticeable ridge or depression; only the 
tips of elytra show a strong reticulation.
