330 SUPPLEMENT. 
when thus viewed, however, it is seen to be sparsely punctured and clothed with white, 
almost pruinose, hairs. The elytra are flattish on their disc, shining, with scarcely any 
metallic tinge. | 
Met with in vast profusion on flowers in the open savannas east from Los Remedios to 
beyond Tolé by Mr. Champion. 
10. Listrus ferrugineus. 
Ferrugineus, fulvo-pubescens ; elytris circa scutellum subinfuscatis, antennis brevibus, articulis duobus penul- 
timis transyersis, ultimo ovato apice nigro. Long. vix 2 millim. 
Hab. Mexico, Northern Sonora (Morrison). 
This is the only species of Listrus known to me at present entirely red in colour, 
but I see no reason to separate it from that genus. The colour is a clear bright, almost 
sanguineous, red. Sometimes the crown of the head is dark, and the extreme tip of 
the claw-joint is, as usual, blackish. 
It was sent by Mr. Morrison, labelled “ Pristoscelis, n. sp.” It is not, however, a 
Pristoscelis, not having the front tibie spinous, nor having upright pile on the body 
above. It appears to have been met with commonly on the border-district of Mexico. 
It is singularly like Dasytiscus precox, a species occurring in Asia Minor, but has the 
antenne much thicker and with shorter joints. 
ASTYLUS (p. 127). 
Astylus vittatus (p. 127). 
To the locality given, add :—Panama, Pefia Blanca (Champion). 
Since the description was published in the earlier part of this volume, this species 
has been captured very abundantly on various kinds of flowers in open savannas from 
the sea-level up to an elevation of 6000 feet; some of the specimens, principally those 
from Pefia Blanca, are of a paler yellow colour. 
2. Astylus octopustulatus. (Tab. XII. fig. 25, ¢.) 
Niger; capite prothoraceque crebre inequaliter, elytris crebre subrugose, punctatis, his maculis quatuor margi- 
neque laterali aurantiaceis. Long. 8 millim. o¢ 92. 
Mas. Elytris apice integris. 
Femina. Hlytris apice profunde excisis. 
Hab. Panama, Bugaba, San Feliz, Los Remedios, Tolé, Pefia Blanca ( Champion). 
Head with a few long erect hairs, some of which surround the eye, closely but very 
finely punctured, subrostrate, owing to the mouth being very prominent; the labrum 
elongate, with a membranaceous space separating it from the epistome; palpi black ; 
antenne black, with four or five joints at the base yellowish, gently serrate from the 
fourth joint. Thorax oblong, with deflexed sides, not margined, but the lateral edge 
sharply defined and a little produced, thickly covered with punctures of two sizes, and
