The Genus Scaphoideus. 



191 



base to apex. Face white, two marginal bands above and two 

 broad fuscous fascia across, one including antennal pits and 

 continued below eyes across pleural pieces of thorax, the 

 other including apical half of clypeus, lower part of cheeks 

 and continued on anterior coxae. Pronotum white with faint 

 infuscatiou, scutellum white, basal angles dark; elytra when 

 closed with a common fuscous cruciate mark as in sanctus, but 

 the hinder bars extend only to the middle of the disk, from 

 whence a fuscous band runs to the suture at apex of clavus, 

 the entire cross bordered with dark fuscous or black; the 

 white base of the clavus parallels the edge of the scutellum, 

 a white bar crosses the clavus obliquely near tip, and hyaline 

 discal and apical spots are bordered with white; post-nodal 

 and two or three apical cells fuscous. Beneath whitish ventral 

 segments bordered with fuscous, and with a fuscous median 

 line. 



Genitalia: 9 last ventral segment concavely excavated; 

 pygofer and ovipositor short, pygofer embrowned at base. 

 cT valve short; plates oval, short, half as long as pygofer, 

 bluntly rounded at apex with a discal brown fascia. 



Four specimens from Port au Prince, Haiti, through the 

 kindness of Mr. E. D. Ball. One specimen cT , Frontera, 

 Mexico (C. H. T. Townsend) is also referred here. 



While the material in hand presents differences that have 

 been thought sufficient to separate this form from the sanctus 

 Say as referred by Van Duzee, it is possible that additional 

 material may connect them, when the range of the species 

 would cover the Gulf States, Atlantic coast of Mexico, and 

 West Indies. However, the vertex is much more obtuse 

 than in P'lorida specimens, especially of males, and the size 

 averages much smaller.
