Bruchus carpophiloides, sp. nov. 

 Plate 13, fig. 8. 



Form slightly elongate. Head too poorly preserved for description. 

 Antennae showing only a few of the intermediate joints which are not 

 serrate but are quite broad. Prothorax produced at the middle of 

 the base into an obtuse lobe, the disk rather finely and sparsely, not 

 deeply punctate, the sides more strongly and closely. Scutellum not 

 visible. Elytra strongly truncate at the apices, punctatostriate, the 

 striae not deep but rather broad, the punctures about as wide as the 

 striae, very slightly elongate, those of the same row practically contigu- 

 ous. Interstitial areas flat, well clothed with short dark hair. Pygi- 

 dium with fine and shallow but close punctuation. Legs wanting. 

 Length, as preserved, 3.90 mm.; to elytral tips, 3 mm. 



Described from one specimen. 



Type— No. 2,651 M. C. Z. Florissant, Col. (No. 7,555 S. H. 

 Scudder Coll.). It is likely that No. 2,653 M. C. Z. (No. 5,393 S. H. 

 Scudder Coll.) represents the same species, while No. 2,652 (No. 7,332 

 S. H. Scudder Coll.) certainly belongs here. 



Related in most of its characters to B. hcnskawi, but is smaller and 

 relatively more slender, the prothorax shining, with finer and sparser 

 punctuation. In B. hetishaun, the strial punctures of the elytra are 

 not in the least elongate but under high power appear a trifle transverse 

 and are stronger and more clearly cut than in the present species. 



Bruchus aboriginalis, sp. nov. 

 Plate 13, fig. 5. 



Form elongate, much broader behind. Head covered by the pro- 

 jecting front margin of the prothorax. Antennae of moderate length, 

 the joints rather strongly serrate, the intermediate ones longer than 

 wide, the remainder not well defined. Pronotum with the front mar- 

 gin strongly arcuate, sides divergent posteriorly to the hind angles, 

 base arcuate but much less than the apex, forming an obtuse lobe. 

 Entire pronotal surface closely, moderately coarsely and distinctly 

 punctured, clothed with short dark hairs. Elytra short, truncate 

 apically, striae not deep nor distinct though rather broad, indistinctly 

 punctate. Interstitial spaces at base punctured like the pronotum.
