Genotype, Amphimela mouhoti, Chapuis (Indo-China). 



This genus was founded by Chapuis for the reception of ao 

 insect from Laos, Indo-China. In the same year Baly described 

 a species which he called Xanthocycla chapuisii from the same 

 locality. It has been determined that these two species are 

 identical. Chapuis regarded the insect as remarkable because the 

 antenna 3 are inserted close to the inner edge of the eyes and are 

 separated by the whole breadth of the forehead ; this condition is 

 unusual among HalticiiN^e, in which the antennae are normally 

 approximated. But the hind femora in this genus are considerably 

 thickened, which is characteristic of Halticiisue. 



Body oval, strongly convex : viewed sideways the highest point 

 of the convexity is just behind the scutellum ; from this point the 

 outline slopes suddenly to the front, and gradually towards the 

 posterior, end. Head broad ; interocular space flat, without any 

 ridges, elevations, or carinas. Antenna? eleven-segmented, slender,, 

 scarcely half the length of the body. Eyes rather large and 

 convex. Prothorax much broader than long ; posterior margin 

 bisinuate on either side of the middle (i. e., with four sinuations 

 altogether), and with a median lobe which is slightly produced 

 backwards ; front margin widely emarginate, fitting to the width 

 of the head. Scutellum sharply triangular. Elytra hardly broader 

 at hase than prothorax, very regular^ pimctate-striate, with a 

 certain amount of space between the rows ; besides the series of 

 punctures the whole surface is very minutely and closely granulate- 

 punctate. Underside: anterior coxal cavities closed ; presternum 

 oblong, with the anterior part broadty dilated; mesosternum 

 almost hidden in the front portion of the metasternum, which lies 

 between the mesocoxa? and is produced behind, reaching between 

 the metacoxas ; posterior femora very strongly dilated : posterior 

 tibiae short, slightly dilated towards the apex, where they are 

 armed with a spine, and channelled on their dorsal side ; claws 

 appendiculate. 



Range. India, Burma, Indo-China. Australia.
