Genus III. Clitena, Baly, Descript. of Uncharacterized, &c., 



Traus. Eut. Soc. Lond. 1864, p. 229. 



Callopistria, Chev. Dej. Cat. p. 402. 



Robusta, subparallela. Caput fortiter punctatum. Thorax trans- 



versus, angulis anticis prominulisj margine anteriore circulariter 



emarginato, lateribus subrotundatis et marginatis, basi subcirculari 



et leviter marginato ; disco Isevi (vix ut in Ccelomera transverse de- 



presso) punctato. Scutellum subquadratum, apice circulari. Elytra 



thorace latiora, parallela, apice rotundata, ante medium transverse 



depressa vel coustricta, Isevia, punctata, nitida. Antenna robustse, 



satis elongatae, art. 1", 3" et4° subaequalibus, art. 2" brevi, art. 5°-l 1'" 



latis compressis, art. 6°-l 1™ brevibus. Pedes robusti, unguiculis bi- 



hamatis. 



Clitena differs from Ccelomera and others in the form of its 

 elytra, which are more robust and antemedially depressed, in the 

 smooth form of the thorax, which shows no trace of the usual 

 deep transverse depression, and especially in the peculiar arti- 

 culation of the antennae, the apical joints of which are flattened, 

 broad, and short. Two species have been described by Mr. Baly 

 — C. limbata and C. melancholica, both from Siam. 



C. cijanea. 



C. Indica, Dej. Cat. 



C. robusta, subparallela, cyanea, pedibus et antennis nigris ; caput 



fortiter punctatum, nigro-cyaneum ; thorax leviter punctatus ; 



scutellum nigrum ; elytra robusta, ante apicem transverse depressa, 



Isevia, punctata ; corpus subtus, antennce, et pedes vel nigra vel 



nigro-cyanea.

Genus IV. Hymenesia. 



Parallela, subdepressa. Caput verticale. Palpi maxillares art. 

 penultimo triangulari, robusto. Thorax transversus, angulis anticis 

 brevibus, posticis rotundatis, disco insequali. Scutellum triangulare, 

 Iseve. Elytra parallela, confuse punctata. Antennce robustse, arti- 

 culis presertim apicalibus insequalibus (subcylindricis, vix depressis), 

 art. r, 3" et 4° subsequalibus, 5°, 6°, T et 8" brevioribus et robustiori- 

 bus, 9° et 2" brevibus, minutis sequalibus 10" et I T conjunctis. Pedes 

 robusti, tarsorum art. basali et 2" penitus sequalibus, unguiculis bipec- 

 tinatis. 



I have formed this genus on the species H. Tranquebarica, 

 Fab. : it is quite distinct, by reason of the very peculiar articu- 

 lation of the antennae, 



H. Tranquebarica, Fab. Syst. El. i. p. 479. 8, Suppl.p.93. 6,7, 

 is punctate and rufous, the antennae, legs, and underside 

 being black ; the elytra are thickly punctate and rufous, the
