Head shining, moderately coarsely punctate above between the eyes, leav- 

 ing, however, a narrow, somewhat elevated smooth space at middle ; frontal 

 tubercles distinct but flat ; antennae scarcely reaching to the middle of elytra, 

 joints rather short and stout, second very smooth, third longer, but scarcely 

 as long as the first, the following joints equal or subequal to the third. Pro- 

 thorax slightly more than twice as wide as long; sides arcuate and feebly 

 narrowing to apex; basal angles distinct, obtuse; apical angles slightly 

 rounded ; surface minutely alutaceous with small, sparsely placed punctures. 

 Elytra not wider at base than the prothorax ; feebly shining, but minutely re- 

 ticulate, and finely punctate, punctures small and well separated. Ventral 

 segments of abdomen shining and relatively very sparsely punctate; feebly 

 pubescent. Length 5 mm. 



Citronella, Alabama. 



I have seen two specimens of this distinct little species and both 

 collected by Mr. Loding; one of these is in his collection. 



From all our vittate species it differs in the position of the dorsal 

 vitta which is situated much nearer to the marginal than to the sutural 

 vitta. In Dr. Horn's arrangement it has to be placed near arizonce. 



Disonycha discoidea Fab. 

 Var. D. abbreviata Melsh. 



One of my specimens of discoidea from Kentucky has on each 

 elytron a pale, subbasal spot in the centre of the black discoidal blotch, 

 and also the apex of this spot is irregularly indented, suggesting the 

 possible occurrence of specimens with a more or less well defined 

 vitta. Vittate specimens would be very near abbreviata, which sug- 

 gested to me the possibility of D. abbreviata being only a variety of 

 D. discoidea. However, my specimens of the former were all from 

 New Braunfels or Brownsville, Texas, and showed sufficient differ- 

 ences to discard this view. Lately in some material, loaned to me by 

 Mr. Wm. T. Davis, I found a specimen from Kentucky which agrees 

 better with Melsheimer's description of abbreviata than the Texan 

 specimens. This is undoubtedly the true abbreviata, which was de- 

 scribed from Pennsylvania, and nothing more than a variety of dis- 

 coida. The Texas specimens look superficially very much like typical 

 abbreviata but show sufficient constant differences to entitle them to 

 a name.
