CERATOBASIS. 
173 
antennae slender, basal joint trigonal, strongly dilated, very slender 
at base. Thorax about two-thirds broader than long, regularly 
cylindrical, feebly narrowed in front, sides straight, posterior 
angles distinct, medial lobe feebly produced, surface entirely 
smooth. Scutellum slightly elongate. Elytra scarcely perceptibly 
punctured, one black spot near suture oblong, the other smaller 
near the margin. Legs, as well as the tarsi, rather long ; anterior 
tarsi distinctly elongate. 
Var. a. Elytral spots nearly indistinct. 
Yar. b. Elytra without any spots. 
Length 4| mm. 
Bab. India. 
It is possible that specimens occur in which the elytra have 
four spots each, since Hiibner speaks of a specimen with an 
additional spot at middle near margin. 
298. Ceratobasis ceylonensis, sp. n. 
Fulvous ; the terminal joints of the antennae and the breast 
black, the head and thorax with two 
black spots ; elytra each with a black 
transverse short band at the base and 
another behind the middle. 
d . Anterior tibiae elongate, strongly 
curved. 
Head fulvous, very broad, transversely 
grooved between the eyes, the latter 
with a black spot in front of each ; 
clypeus with a shallow semicircular de- 
pression, triangularly emarginate at the 
sides and in the middle ; labrum black ; 
antennae black, extending to the base of 
the thorax, the basal three joints fulvous, 
basal joint strongly, subquadrately 
widened, fourth and following joints 
transverse. Thorax twice as broad as 
long, the sides and the posterior angles 
rounded, the basal margin scarcely lobed at the middle; the 
surface convex, impunctate, fulvous, with two widely separated, 
black, elongate and slightly curved spots, not extending to the 
anterior but to the posterior margin. Scutellum triangular. 
Elytra fulvous, subquadrate, without basal humeral lobes, very 
minutely granulate and impressed with fine very obsolete 
punctures, the basal margin raised into a fine ridge ; each elytron 
with a transverse, short, black band below the base and another 
one, slightly narrowed at its inner portion, behind the middle, 
neither of these bands extends to either margin. Anterior coxa? 
black, rest of the underside and the legs fulvous, anterior femora 
and their tibiae with a narrow black upper edge.
