QTNANDROPHTHALMA. 103 



Genus GYNANDROPHTHALMA. 



Gynandrophthalma, Lacord. Mon. Phytoph. ii, 1848, p. 256 ; Chapuis, 

 Gen. Co-opt, x, 1874, p. 12. 



Type, G. nigropunctata, Lacord., from South America. 



Range. Distributed more or less over both hemispheres. 



Size generally rather small ; shape elongate and subcylindrical or 

 shorter and more ovate ; above nearly always glabrous. 



Head rather short ; mandibles small ; eyes variable ; antennae 

 comparatively slender, second and third joints short and equal, the 

 following joints transversely serrate. Thorax transverse, short, 

 variable, posterior angles distinct or rounded. Elytra generally 

 without distinct epipleural lobes. Legs rather short, the anterior 

 legs often slightly longer than the others. Tarsi variable, first 

 joint longer than the second. 



This is not a well-defined genus owing to the variability of the 

 structural characters, but may be recognized by the absence of 

 elytral lobes (indicated in a few cases), generally small size, and 

 by the other characters given above. 



Elytra Hack with apex pale.

 Belg. xli, 1897, p. 422. 



c? . Fulvous ; apical joints of antennae black ; elytra black, 

 extreme apex fulvous. Elongate and parallel-sided ; head broad, 

 impunctate, with a very shallow groove between the eyes, the 

 latter round and entire ; clypeus separated from the face by a 

 semicircular row of foveae, anterior margin subtriangularly emar- 

 ginate, sides below the eyes thickened ; mandibles broad and 

 robust, the left mandible excavated at base, apex black ; antennae 

 fuscous, comparatively long and slender, basal four or five joints 

 flavous, second and third small, fourth and following triangularly 

 widened. Thorax generally twice as broad as long, sides and 

 posterior angles rounded, anterior margin only slightly narrower 

 than the posterior margin ; surface impunctate ; median lobe 

 scarcely indicated, preceded by a short impressed line. Scutellum 

 fulvous, apex raised and thickened. Elytra very slightly narrowed 

 at base, scarcely lobed at the sides, sparingly and minutely 

 punctured, the punctures arranged in irregular rows ; apical 

 margins narrowly flavous. Legs elongate, first joint of tarsi double 

 the length of the second (in the original description this joint 

 is erroneously described as " scarcely longer than the second ") ; last 

 abdominal segment of female with a deep fovea. $ . Antennae 

 shorter, head and thorax narrower, legs less elongate. 



Length 5 mm. 



Hab. Bengal : Mandar. 



Much larger than G. delesserti, Lacord., and without thoracic 

 black baud, head differently coloured.
