462 Mr. Baly's descriptions of 



four or five double rows, interspaces impressed witli punctiu-es, 

 scarcely fiutir thau those on the rows themselves, and so reudcr- 

 ina: them still less distinct. 



Genus eustetha, Baly, 

 1. Eustetha limbata, n. sp. 



Oblongo-ovata, convexa, nigra, nitida, cyaneo vix tincta, 

 abdomine elytrisque flavo-fulvis, his substriatim punctatis, 

 vitrisque limbo, apice dilatato, nigro-piceo: thorace transverse, 

 utrin(pie transversim sulcato, disco sparse et tenuiter, lateribus 

 magis profunde punctatis. Long. 3-3^ lin. 



Hab. The Plains. 



Vertex shining, nearly impunctate; encarpa3 transverse, quad- 

 rangular, contiguous, separated by a deep longitudinal groove, 

 which extends downwards for a short distance on the clypeus; 

 the clypeus itself thickened, trigonate ; antennas nearly three- 

 fourths the length of the body, the second and third joints very 

 short, equal, the fourth and following ones compressed, not 

 dilated, the fourth nearly equal in length to the preceding three 

 united. Thorax three times as broad as long ; sides parallel, 

 very slightly curved, the hinder angles aciite, the anterior ones 

 thickened, obliquely truncate, produced laterally into a short • 

 acute tooth; upper surface transversely sulcate on either side, 

 the sulcation terminating at some distance from the lateral 

 margin in a large deep fovea. Scutellum shghtly longer than 

 broad, trigonate, its apex obtuse. Elytra broader than the 

 thorax, the sides parallel, the apex rounded; above convex, each 

 elytron with the whole limb (dilated at the apex) nigro-piceous ; 

 on the disc of each are four ill-defined double rows of punctuj-es, 

 the interspaces between which are impressed with punctures 

 rather finer than those on the rows themselves; inflexed limb 

 shining black. 



Genus acroxena, Baly, n. gen. 



Corpus elongatum. Caput exsertum; oculis rotundatis, pro- 

 miuentibus; antennis robustis, ad apicem attenuatis. Thorax 

 transversus, dorso non impressus. Elytra thorace latiora, 

 parallela, modice convexa, infra basin non excavata, confuse 

 punctata; limbo reflexo fere ad apicem extenso. Pedes modice 

 robusti, simplices ; coxis anticis magnis, contiguis ; tibiis apice 

 muticis; unguicidis appcndicidatis. Prosternum medio coxis
