Elytral strife indistinctly punctate, except the strise at sides, which consist each 

 of a row of coarser punctures ; the first interval confusedly punctate with large 

 punctures, surface shining Carinifrons Bates. 



18. First joint of hind tarsi shorter than second ; first elytral interval divided by an 



irregular row of punctures, the second with a few very obsolete punctures, cly- 

 peal margin very broadly reflexed, color testaceous, head, scutellum, suture and 



a large thoracic spot of irregular outline darker semilivida Lee. 



First joint of hind tarsi as long as second ; first elytral interval coarsely and con- 

 fusedly punctate, second with a row of coarse punctures ; clypeal margin mod- 

 erately reflexed ; color testaceous ; head, a large thoracic spot attaining the base, 

 suture and sides of elytra dark brown minuta Burm. 



19. Pygidium shining, punctured, the punctures on the disk generally well 



separated 20. 



Pygidium subopaque, densely rugose and pubescent 21. 



20. Thorax shining, punctuation sparse, testaceous, with or without discal piceous 



space or entirely black, elytra from testaceous to black lucicola Fab. 



Thorax subopaque, very densely punctured with aeneous luster, side margins pale ; 

 elytra testaceous to castaneous Oblivia Horn. 



21. Thora.x coarsely punctured, shining, dark rufescent, with slight ?eneous luster, 



side margins pale marginata Fab. 



Strigoderma latitibia, new species. 



Form of pygDusa but larger ; elytra dark brown to fulvous ; head and thorax 

 brownish-metallic, in the paler specimens with side margins also pale. Head and 

 clypeus coarsely and densely punctate ; clypeal suture impressed ; clypeus moder- 

 ately reflexed. Thorax twice as wide at base as long ; sides arcuate slightly before 

 middle, parallel behind, obliquely narrowing to front angles, which are right ; 

 surface coarsely and rather densely punctate, feebly impressed on each side, sparsely 

 clothed with moderately long pale hairs. Scutellum with a few coarse, irregularly 

 distributed punctures. Elytra slightly longer than wide, feebly arcuate at sides ; 

 three or four striae nearest suture, regular, the others more or less confused, rather 

 coarsely punctate. Pygidium rugose. Front tibia; bidentate ; front and middle tars 

 cleft, the upper division finer than the lower; hind tibiae wide and short, about twice 

 as long as wide at apex. Last abdominal segment finely and densely punctulate, the 

 other segments much coarser and sparser. Under side and legs sparsely pubescent' 

 with cinereous hairs. Length 8 mm. 



Galveston, Texas (F. H. Snow). 



This species will be readily identified by the short and broad 

 hind tibiae of the males, which is the only sex known to me. 



The form is similar to pygmcea but larger ; the color is variable, in 

 the pale specimens the sides of elytra are darker and the sides of 

 thorax pale. The elytral sculpture is similar to that oi pygincea, but 

 the striae are not quite as deeply impressed.
