2 GO llcv. II. Clark on Dejean's Genus Coelomera. 



apex being marked by a purple transverse band, which broadly 

 extends, near the margination, for nearly half the elytra. The 

 length is 4|, breadth 2h lines. From the East Indies. 



Genus V. Ohtiioxia. 



Subparallela et satis depressa. Caput verticale. Palpi maxillares 

 articulis apicali et penultimo globosis. Thorax transversus, margine 

 antieo transverso, lateribus subrotundatis, margine postico sinuato, 

 angulis anticis vix prominentibus, disco in typo insequali. Scutellum 

 triangulare. Elytra thorace paulum latiora, parallela. Antenna 

 robusta?, serratse, articulis (presertira 3"-7 m ) apud apices incrassatis, 

 art. 3°— 7 m longitudine subsequalibus. Pedes robusti ; unguiculis ad 

 apices extremos, bihamatis. 



This genus is nearly related to Monocesta, but differs from it 

 in the globularly inflated maxillary palpi, in the minute bifurca- 

 tion of the unguiculi (those of Monocesta being cleft almost to 

 the base), and the serrated articulation of the antennae.

Genus VI. Pyesia. 



Differt a genere Monocesta in antennis art. 3° primo breviorc, tenui, 

 art. 4° tertio multum longiore, art. 5° et 6° subsequalibus et tertio 

 paulum longioribus ; antennis in § simplicibus, filiformibus ; in 3 

 art. 4°-7 ra dilatatis, compressis. 



P. laticornis, Germ. Insect. Spec. 589, 843. 



Closely allied in pattern to M. consularis, Dej., but a much 

 smaller insect, and more depressed in form ; the elytra are not 

 finely rugose, but levigate and punctate. The articulation also 

 of the antenna;, both in $ and <$ (which is the special character 

 of the separate genus into whicli it must be erected), abun- 

 dantly distinguishes it from this insect.

Genus VII. Procalus. 



Itobustus, parallelus, brevis. Caput verticale. Palpi maxillares 

 elongatuli. Thorax magnus, transversus, vix elytra amplitudine
