head sub-acute, with two minute fuscous points near the 

 tip, and an undulated line on the anterior edge; thorax 

 dusky across the middle; hemelytra white, somewhat 

 opalescent, with a common large cruciform mark on the 

 middle composed of brownish spots with blackish edges, and 

 including a whitish common spot; tip with large spots; 

 venter with a dusky band and small lateral spots; feet 

 immaculate. Length to tip of hemelytra nearly one-fifth of 

 an inch." (Say.) 



The form which Van Duzee has referred to sanctus Say 

 occurs in Florida, Mississippi, and Texas, but I know of no 

 specimens from the latitude of Indiana, the type locality. 

 The specimens which formed the basis of Van Duzee's refer- 

 ence agree in most respects with Say's description, but pos- 

 sess two dark fasciae across the face, a point not mentioned in 

 Say's description. There are also fuscous annulations on the 

 legs, which would seem to be excluded by the "feet immacu- 

 late" of Say's description. On the other hand my picturatus 

 occurring nearer the type locality agrees very well in these 

 respects, but has the vertex entirely too prominent and sharp 

 to be called "sub-acute." It seems, therefore, the better plan 

 to follow Van Duzee's reference until sufficient material is 

 available to determine positively that it should be changed. 

 A change, if not supported by future collecting in the type 

 locality of Say's species, would only add greater confusion, 

 which should be avoided if possible. 



The specimens of this form in hand, and which include 

 the Florida specimen of Van Duzee's reference, have the 

 head sub-acute with four distinct transverse spots on the 

 vertex behind the transverse impression, and in some there 

 is a trace of a minute pair of apical dots. The band on pro- 

 thorax is finely transversely irrorate in female, and broken 

 into four oval black spots in the male. The last ventral seg- 

 ment of female is very short, bisinuate, and with an elevated 

 polished black area at middle. The male vertex is slightly 

 more produced, and the genital valve is very small, oval, the 

 plates short and oval with a dark submargin. As compared 

 with the Haitian species, fasciatas, the vertex is much more 

 acute, and the marks on head and pronotum more distinct. 

 Specimens from Texas show some tendency to vary between
