BLACKBURN AND SHarP—On some New Species and Genera of Coleoptera. 165 
Cis roridus, n. sp.—Parallelus, angustulus, sat elongatus, parum nitidus cre- 
brius conspicueque setulosus, dense fortiter punctatus, fuscus, antennarum basi 
pedibusque rufis, prothorace anterius testaceo, elytris maculis plurimis testaceis. 
Long. 12 m.m. 
Antennz dark, with the two basal joints reddish; thorax about as broad as 
long, very densely punctate, finely and indistinctly margined ; elytra coarsely and 
closely punctate, marked with conspicuous pale yellow spots, one on each side of 
the scutellum, and one more elongate between this and the shoulder, and nearly 
attaining a spot near the suture in front of the middle; beyond the middle an 
oblique transverse mark. 
This species is another very distinct one; the peculiar clothing of the upper 
surface (which consists of a pale, rather rough setulosity, somewhat like what is 
frequent in the genus, but more elongate and finer) is of itself sufficient for its 
identification.

Cis attenuatus, n. sp.—Oblongus, angustus, parum convexus, supra testaceus, 
elytris in medio nigro-signatis, opacus, dense punctatus, brevissime hispidulus. 
Long. 14 m.m. 
This species, by its very dense punctuation and other characters, is closely 
allied to C. signatus, of which I formerly treated it as a variety (Trans. Ent. Soc., 
1879, p. 93); the thorax is, however, longer and less transverse, and its punctua- 
tion rather less dense ; the general form is a little narrower and more cylindrical, 
and the eyes are a little smaller; the antennz are entirely yellow, and the thorax 
is without the large black mark of C. signatus. I think, therefore, this will prove 
a distinct species, even should the colour distinctions, as is probable, prove incon- 
stant. 
Found on the mountains of Kauai, and formerly thought to be a variety of C. signatus.

Cis ephistemoides, n. sp.—Ovalis, valde convexus, nitidus, glaber, impuncta- 
tus, subtus testaceus, supra nigricans vel piceus, antennis’ pedibusque testaceis, 
antennarum clava fusca. Long. 1 to 11 m.m. 
This insect differs so much in form and appearance from the other species of 
Cis, that I supposed it would prove to be a distinct genus, and allied probably to 
Atomaria or Ephistemus, of which it has much the facies, but on examination 
Iam unable to find any good characters to distinguish it from Cis. The rather 
slender antenne are of the form usual in the genus with three-jointed club. The 
thorax is extremely convex transversely and much longer in the middle than at
