ilarly subdecumbent and fulvous but is denser than in Aleo- 

 chara, and the body has somewhat the same stout compact 

 build, differing in many minor points, such as the relatively 

 less developed prothorax with better defined hind angles. 

 Our only species may be described as follows : — 



Rather stout, convex, shining, piceo-castaneoas in color, the abdomen 

 black, each elytron obliquely shaded with dark rufous on the disk from 

 the humeri toward the sutural apex; antennae blackish, gradually 

 paler toward base, the legs pale; head moderate, rather wider 

 than long, fully half as wide as the prothorax, finely, rather closely 

 punctulate; antennae longer than the head and prothorax, grad- 

 ually and moderately incrassate distally to the tip, the eleventh joint 

 elongate, subpyrlform, the tenth about one-half wider than long, the 

 second and third elonaate and equal; prothorax nearly three-fourths 

 wider than long, the sides strongly, anteriorly converging and rather 

 feebly arcuate, the base broadly, circularly arcuate, the angles evident 

 though well rounded; pumtures fine, even and dense throughout; 

 elytra at the sides as long as the sides of the prothorax, continuing the 

 curvature of the latter, but becoming paralled and arcuate posteriorly, 

 the suture three-fourths as long as the prothorax, the punctures fine, 

 asperate and very dense throughout; abdomen at base as wide as 

 the apex of the elytra, rather strongly, evenly narrowed thence to the 

 tip, less finely and closely punctate than the elytra. Length 3.75 mm.; 

 width 1.22 mm. Texas (Galveston). \^= Baryodma bip.,Csy.']. 



bipartlta Csy. 



This species was erroneously described as a Baryodma. 

 There are two other species of the genus known to me, one 

 inscribed in the European lists as Xenochara puberula Klug, 

 differing from hipartita in its narrower form, less converg- 

 ing sides of the prothorax, relatively less dense punctuation, 

 somewhat larger head and in the form of the metasternal 

 projection — very broadly rounded and subobsolete in puber- 

 ula and more abruptly and parabolically rounded at the middle 

 in hipartita^ — and a species identified for me by Mr. Reitter 

 as Baryodma milleri Kr. The latter of these species is larger 

 than j9M6e?'«?a, blacker in color and with a smaller head, the 

 oblique rufous band of each elytron, characterizing jow^erw^a , 

 being obliterated toward the humeri, resulting in an angulate 

 rufous apical spot. The identification of the species may not 

 be correct, but the specimen before me was collected in the 

 Caucasus.
