326 SUPPLEMENT. 
1. Holomallus aurivillus. 
Nigro-fuscus ; elytris, abdomine pedibusque ferrugineis; dense aureo-villosus, sutura pone medium elevatiori. 
Long. 5-6 millim. 
Hab. Mrxico, Puebla (Salle). 
The head and thorax are dark fuscous, almost black, the former very closely and 
finely, the latter less closely and more deeply, punctured ; both are very hairy, but the 
hairs upon the head are shorter and more scattered than on the thorax. The elytra 
appear to be rather thin in texture, widening a little behind the middle, but rather 
acuminate as well as depressed at their apex; their punctuation is nearly hidden by 
the dense and long golden-yellow pubescence, but is quite distinct, and here and there 
confluent; in the larger of the two specimens there is a faintly infuscate spot towards 
their apex. The abdomen is rusty red, but the extreme base and the apex are dark 
fuscous. The legs are red, the tibie clothed with long hairs externally. 
There is a third specimen from Puebla, in Sallé’s collection, of a species perhaps not 
distinct from the foregoing, but which is comparatively destitute of hair, and has, 
moreover, the elytra of the same dark fuscous colour as the head and thorax, excepting 
alone the apical, depressed, gibbous portion, which is rusty red, and clothed indistinctly 
with short greyish pubescence. Whether this specimen belongs to a distinct species 
or not it is impossible to say from the single individual. 
DASYTES (to follow the genus Holomallus). 
Dasytes, Paykull, Faun. Suec. ii. p. 156 (1798). 
The type of Dasytes is D. niger (Linn.), a well-known European species. Mulsant’s 
division of the insects usually comprised under this name has not at present met with 
general acceptation, and as the only species in the Central-American fauna is not 
sufficiently distinct to render its separation of any practical utility, it is not neces- 
sary here to enter on the question of how far those divisions are natural. The 
typical species are oblong hairy insects of small and generally uniform size, with 
serrate slightly thickened antenne and subulate palpi; these are almost confined to the 
European and Mediterranean regions, where they usually abound when found in flowers ; 
the earlier stages of some at least (e.g. D. niger) are passed in decaying wood. 
1. Dasytes hudsonicus. 
Dasytes hudsonicus, Leconte, Proc. Ac. Phil. xviii. p. 360 (1866) *. 
Hab. Nortu America, Hudson’s Bay :—Mexico, Northern Sonora (Morrison). 
This is a black rather depressed species with almost simple antenne, nearly smooth 
front tibie, and a short thorax with an impressed line on each side, between which and 
the margin the edge of the thorax is more thickly and rugosely punctured. It appears 
to be common in the border country of Northern Mexico and Texas, and therefore to 
have a wide range of distribution.
