The hind tibiae are also very distinctive. The intensity of the 

 colours varies considerably: on many specimens the head, 

 prothorax, metasternum, and abdomen appear to be of a livid- 

 brown, with a distinct metallic gloss, on others the colour is 

 so much darker that they appear to be almost black, with a 

 conspicuous greenish gloss; the knees (frequently only the hind 

 ones), some (or none) of the tarsal joints, and the tips of from 

 one to five of the apical joints of antennae are more or less 

 infuscated. 



Geloptera tuberculiventris, n. sp. 



cf . Of a livid greenish-bronze, the elevated parts more 

 or less coppery ; appendages flavous, some parts infuscated. 



Head with several impunctate spaces, elsewhere with 

 crowded punctures, denser at base and on clypeus than else- 

 where. Protliora.r somewhat uneven, with three small 

 impunctate spaces, each side with two feeble submedian teeth ;. 

 punctures dense and moderately large. Eli/fra w^ith regular 

 striae and interstices only on apical slope, but elsewhere the- 

 punctures (which are generally slightly larger than those on 

 prothorax) frequently have a sublineate arrangement. Basal 

 segment of ahdovitn with a large obtuse tubercle, fourth longer 

 than second and third combined, fifth with a small median 

 fovea. Hind tibiae curved, dilated and compressed in middle ; 

 basal joint of four front tarsi inflated. Length, 5-5^ mm. 



9 . Differs in having the abdomen strongly and evenly 

 convex, basal segment non-tuberculate, fourth no longer than 

 third, fifth non-foveate, hind tibiae shorter and simple, and 

 in the tarsi.

Of the antennae the fourth to eleventh joints are each 

 partly infuscated, the knees and middle of tibiae are also' 

 infuscated. At the basal third of elytra some of the punctures 

 are transversely confluent.

d . Colours much as in preceding species. 



Head, profliorax, and elytra much as in preceding species,, 

 except that each side of the prothorax is obtusely undulated 

 about the middle, leaving but one obtuse median tooth. Basal 

 segment of ahdomen depressed in middle, fifth very short in 

 middle. Hind tibiae long, rather strongly curved about apex, 

 terminated by a recurved hook, upper-surface longitudinally 

 concave near apex : basal joint of four front tarsi strongly 

 inflated, of the hind ones unusually long. Length, 4| mm.
