108 CHETSOMELID^E. 



Whether the differences IB 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-maculata the corresponding spots are wide apart and placed 

 lower down. 



191. Gynandrophthalma cornuta, Jac. (Titubcea) Ann. Soc. JEnt. 

 Belg. 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. 



<5 . 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 tour 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 

 .p. 04 feebly lobed at base, very finely and rather 



Gynandrophthalma closely punctured, a sutural spot below the 

 cornuta. scutellum, the other markings as given above. 



Base of femora and abdominal segments 



more or less fulvous; anterior legs and tde metatarsus rather 

 elongate. 



Var. a. Humeral spot prolonged to apex and joined to posterior 

 band, both very broad. 



Var. 6. Humeral spot obscure, all other markings absent. 

 Length 6-8 mm. 

 Hab. Kanara, Belgaum. 



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 oi: the thorax, which is widened at the sides 

 posteriorly in the last named species but of equal width in the 

 present insect. The species caunot remain in Titubcea (Miopristis) 

 as the anterior legs are only slightly more elongate than the 

 others. The structure of the head of the male is quite unique.
