CHRYSOMELIDJE. 
Whether the differences in coloration of the scutellum and legs 
are constant in the two sexes it is impossible to say, as only two 
specimens are before me. The species much resembles G. 8-macu- 
lata, Jac., but may be known by the black vertex of the head and 
the markings of the thorax ; another difference is in the position 
of the elytral spots ; in the present species the lower two are 
nearer together and placed immediately behind the middle, in 
G. 8 -mciculata the corresponding spots are wide apart and placed 
lower down. 
191. Gynandrophthalma cornuta, Jac. (Tituboea) Ann. Soc. Ent. 
Bely. xxxix, 1895, p. 259. 
Fulvous, more or less black beneath ; base of head and two trans- 
verse spots on thorax blackish blue. Elytra with a lozenge-shaped 
spot at base, an elongate spot on shoulders, a transverse dentate 
band behind the middle and a sutural spot at apex, dark blue. 
c? . Head with an acute horn-like projec- 
tion between the eyes, entirely impunctate ; 
clypeus not separated from face ; labrum 
fulvous, mandibles robust, broad, concave 
above and angular ; antennae scarcely ex- 
tending to base of thorax, basal four joints 
fulvous ; the others fuscous, fifth and follow- 
ing joints moderately widened. Thorax 
nearly three times as broad as long, sides 
feebly rounded, angles distinct, posterior 
angles more obtuse, disc impunctate. Elytra 
feebly lobed at base, very finely and rather 
closely punctured, a sutural spot below the 
scutellum, the other markings as given above. 
Ease of femora and abdominal segments 
more or less fulvous ; anterior legs and tne metatarsus rather 
elongate. 
Yar. a. Humeral spot prolonged to apex and joined to posterior 
band, both very broad. 
Yar. b. Humeral spot obscure, all other markings absent. 
Length 6-8 mm.

In the female the head is simple and the thorax less transverse. 
In both sexes the first joint of the anterior tarsi is as long as the 
following two joints united. It is a large species subcylindrical 
in shape, well distinguished by the shape of the elytral markings. 
The unspotted variety can be distinguished from G. fuscitarsis, 
Jac. by the shape of the thorax, which is widened at the sides 
posteriorly in the last named species but of equal width in the 
present insect. The species cannot remain in Tituboea ( Miopristis ) 
as the anterior legs are only slightly more elongate than the 
others. The structure of the head of the male is quite unique.
