Acropteroxys gracilis var. texana new variety. 



A form taken rather commonly at Brownsville. Tex., agrees with typical 

 gracilis except that the prosternum around the front coxa is black as in divisa 

 Horn. The black prothoracic spot is as in gracilis, that is, longitudinal. In 

 divisa it .generally covers more or less the entire base. 



Brownsville, Texas. ' 



Triplax mesosternalis Schaef. 

 Triplax vwnostignia Casey. 



Typical mcsostcrualis bave tbe protborax with three anterior black 

 spots, one at tbe middle of anterior margin and one on each side near 

 tbe lateral margin. Tbe central spot is always distinct but tbe two 

 lateral spots are sometimes only faintly indicated or entirely absent. 

 I have specimens from Colorado, Arizona and New Mexico. 



Chrysobothris sexfasciata new species. 



Very similar in form and coloration to C. chrysala. Head feebly convex 

 in front ; eyes relatively narrowly separated and connected above by an arcuate 

 carina, occipital carina faint ; clypeus more or less distinctly triangularly 

 emarginate at middle, subtruncate each side ; antennas nearly as in chryscela 

 but with the third joint slightly shorter. Prothorax transverse, sides arcuate 

 each side ; disc moderately convex without depressions or callosities ; punctua- 

 tion moderately coarse, punctures at sides near base larger and separated by 

 more or Uss distinct narrow ridges. Elytra wider than the prothorax; the 

 margin serrulate; disc without trace of costse ; basal fovea. deep, median fovea 

 faint ; a green basal fascia connected at sides with a slightly arcuate submedian 

 fascia ; a slightly oblique postmedian fascia and the extreme apex of the same 

 color; surface moderately coarsely punctate, disc without costse ; near the' 

 lateral margin from the submedian to thesubapical fascia a more or less dis- 

 tinct and more coarsely and closely punctate impression. Ventral segments 

 moderately coarsely punctate ; lateral margin of last segment entire, apex en- 

 tire and slightly arcuate, without acute angles. Prosternum rather truncate ; 

 anterior femur with an acute tooth, not serrulate within. Length 4.5 mm. 



Key West, Florida. 



Type in the collection of tbe Brooklyn Museum, received tbrotigh 

 the kindness of Mr. Alan S. Nicolay. 



This species is apt to be taken for a small clirysivla, which it re- 

 sembles very closely. It differs, however, from that species in having
