Prakasha, gen. nov. 



In Ann. Mas. Civ. Gen. 1892, p. 333, Bates described 

 Phtti/iiiefopus (?) aniariformis, but remarked at, tiie end of the 

 description, "The head is small and presents none o£ the 

 peculiarities of tlie typical Platijmetopi.'''' The genus is 

 nearer Diorijche than Platymetopus, but the form of the head 

 and some other characters render a new genus necessary. 

 The ligula and paraglosste are as in Dioryche, mentum 

 witliout tooth, but with the emargination tliickened in 

 niiddle ; penultimate joint of labial palpi plurisetose. Form 

 broad, surface smooth, colour aineous. Head small, smooth, 

 convex, not depressed in front, clypeus only slightly emar- 

 ginate, not exposing basal membrane of labrum; frontal 

 fovege small, curving oufwards behind and continuing as a 

 fine line to the eye ; antenna hardly reaching base of pro- 

 thorax, very finely pubescent from middle of joint 3 ; eyes 

 prominent. Elytral intervals 3,' 5, and 7 with a row of 

 punctures. Tarsi smooth on upper surface ; front and inter- 

 mediate tarsi in ^ with four moderately dilated joints, 1 

 rectangular, 2, 3, and 4 triangular, biseriately squamose 

 benejitli. 



The generic name is derived from a Kanarese word 

 meaning " lustre." 



P. amariformis^ Bates, from Kawkareet (Tenasserim) and 

 Taun-ngu, is the genotype and sole representative of the 

 genus. 



Amhlysiomus vittaius, Bates, Ann. Soc. Ent. Belg. 1892, 

 p. 231. 



The name is preoccupied by A. vittatus, Gestro, Ann. Mus. 

 Civ. Gen. 1875, p. 885, and for Bates's species I propose the 

 name of A. hivittatus. 



Anoplogenius patina/is, Bates, Ann. Mus. Civ. Gen. 1892, 

 p. 'd4:G = Le]n(hri.v foliolosus, Nietn. Journ. As. Soc. 

 Beng. 1857, ii. p. 152 = Aiioplogenius discophorus, Chaud. 

 Bull. Mosc. 1852, i. p. 90. 



Acupalpus marginatxis, Bates (not Lucas), Trans. Ent. Soc. 

 Lond. 1883, p. 241. 



A note by Mr. Bedel, in his Cat. rais. des Col. du Nord 

 de I'Afr. 1899, p. 158, note (2), induced me to examine the 

 example in the British Museum, which I find to be A. 

 dorsa/is, F.
