KYPHOCOTIS Kirk- 
H.S.P.A. Exp. Sta. Bull. 1 (9) ; 370, 1900. 
Four described species belong to this genus : tessellata Kirk. (1906, 07) (Tyj)e) ; 
fasciata Dist., jwm Dist., nigrescens Dist. (1907). It is probable that K. 'parva is 
synonymous with the genotype. 
Although as with other genera the sexes dift'er from each other in size, they 
resemble each other in colour pattern and can be readily correlated. Kirkaldy in 
describing this genus cites only one character, which concerns the scutellum : “ The 
posterior three-fifths of the scutellum are elevated in a narrow acute crest. This 
character is only of specific value, since species occur which are obviously congeneric 
with the genotype, yet have the scutellum flat. A re-description of the genus follows. 
The head ventrally is flat anteriorly and the maxillary })Iates extend along- 
side but not beyond the clypeus. The antennal ledges are distinct and terminate 
at the frontal sutures. The hind margin of the frons which is barely perceptible, lies 
well forward of the apex of the head and the vertex lias a slight median longitudinal 
ridge. The crown of the head is of even width throughout and the eyes are prominent. 
The pronotum is raised posteriorly, and the posterior half is transversely striated, the 
postero-lateral angles are raised into one or two short rounded ridges. The scutellum 
which is transversely striated is flat, or raised posteriorly into a hump of variable 
elevation. The tegmina which are rounded apically and have the veins raised in 
relief, are an opaque brown or grey. The hind tibiae have three rows of small spines 
and a row of five flattened spurs. 
cj, seven -tenths the length of the $. 
The tegmina are largely transparent and narrow apically. 
ANACOTIS gen. nov. 
The head is flat anteriorly, and the maxillary plates extend alongside and 
beyond the ajjex of the clypeus, and the labium reaches as far as the middle coxae. 
The antennal ledges are distinct and extend across the frontal sutures, the two ridges 
meeting medianly on the frons ; anterior to their junction the frons is slightly raised, 
posteriorly it is depressed, with a median longitudinal ridge. The crown of the head 
is wider medianly than laterally, the apical margin is uneven, and the ocelli lie well 
away from the a])ical border on the sides of outwardly facing ri<ig(‘H. The eyes are 
prominent. The pronotum and scutellum are transversely striated, the latter being 
raised into a low hump posteriorly. The tegmina narrow apically and the radius is 
many-branched. The fore and middle femora arc flattened and the hind tibiae have 
three rows of short spines and one row of eleven flattened spurs. The sub-genital 
plates are short and narrow, not extending as far as the apex of the pygophores. (In 
Stenocotis the sub-genital plates extend well past the pygophores.)
