SCOTT—COLEOPTERA; HYDROPHILIDA, HISTERIDA 201 
Régimbart first described specimens from Aldabra as cupreus: in 1903 (U.c.) he 
stated that he considered this a synonym of denticulata: and again in 1906 (l.c.) he 
considered that this was a mistake, and that the Aldabra specimens were referable not to 
denticulata, but to stagnicola. The name cupreus then became a synonym of stagnicola, 
and as such it is given by Zaitzev in his Catalogue (1908, p. 362). 
In the absence of types wherewith to compare it, I refer a single 3, which agrees with 
Régimbart’s descriptions, to this species. Length, including the extended head, 5mm. ; 
palps reddish, legs black, slightly ferruginous : head fairly closely punctured : thorax less 
closely punctured in the middle, nearly as closely as the head at the sides: elytra with 
the two strize nearest the suture effaced towards the base over about + of their length, 
the 3rd and 4th faint towards the base, the 5th reaching almost to the base, the 6th and 
7th abbreviated a little before the base (the 6th ending in the region of the callus, in 
which region its punctures become widely spaced out, and the 7th ending a trifle further 
from the base than the 6th), and the 8th, 9th and 10th (ze. the outermost) reaching 
practically to the base: striz much deeper behind, crenulate-punctate : the punctures of 
the intervals much finer than those of the strize, and the hairs which they bear extremely 
short and fine and hard to see (possibly the specimen is worn; but the pubescence is less 
conspicuous than in several specimens determined as V. enews Brullé which I have before 
me). 
Loc. Aldabra: Takamaka, 1908, 1 g¢ (Fryer); 1895 (Voeltzkow). Volvulus 
stagnicola is widely spread in Tropical Africa (see Régimbart, 1906, l.c.: V. denticulatus 
is known from Madagascar).

Supra nigro-zeneus, prothoracis lateribus et elytrorum apicibus obscure rufescentibus, 
antennis palpisque rufo-ferrugineis, antennarum clavis atque articuli 4' palporum apice 
infuscatis ; subtus capite, meso- et metasternis, abdomineque nigris, prosterno pedibusque 
rufo-ferrugineis : capite pronoto elytrisque dense fortiter punctatis: mesosterno pone 
dentem anteriorem carinula longitudinali instructo ; femoribus mediis pubescentid haud 
ultra medium attingente. Long. corp. 2 mm. 
Shining, with a strong brassy lustre; antennze, palps and legs rather dark reddish ; 
beneath, the head, meso- and metasterna and abdomen are black, while the prosternum is 
reddish. The species is characterised by the strong and dense punctuation of the upper 
surface : on the head the punctures are very small near the anterior margin, larger behind, 
the largest being on either side near the eye ; on the pronotum the punctures are a little 
finer and further apart than those on the elytra: on the elytra they are densest and 
largest, often not separated by much more than their own diameter, and especially close 
in the scutellar region. The elytra have no trace of seriate punctuation: the sutural 
stria is well marked, abbreviated in front. Under high power the elytral punctures 
appear simple and circular.
