GYNANDROPHTHALMA. 
103 
Genus GYNANDROPHTHALMA. 
Gynandrophthalma, Lacord. Mon. Phytoph. ii, 1848, p. 256 ; Chapuis , 
Gen. Coleopt. x, 1874, p. 12. 
Type, G. nigvopunctata, Lacorcl., 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 black with apex pale.

6 . Eulvous ; 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. — $ . Antennas 
shorter, head and thorax narrower, legs less elongate. 
Length 5 mm. 
Hob. Bengal : Mandar. 
Much larger than G. delesserti, Lacord., and without thoracic 
black band, head differently coloured.
