b4 STUDIES IN NORTH AMERICAN MEMBR ACID.-E 



tion given by Stal in the Hemiptera Fabriciana but it answers 

 better than any other known to me, audit is the species determ- 

 ined as muticus by Dr. Uhler according to a specimen in the 

 Cornell University collection. The specimens I have recorded 

 above vary much in the depth of color but I believe they per- 

 tain to one species. 



5. Cyrtolobus tuberosus Fairmaire. PI. 2, fig. 18. 



Large and strongly marked with an elliptical crest placed 

 well back. Pronotum moderately elevated, crest rather abrupt, 

 reaching from behind the humeri to or nearly to the apex of 

 the abdomen, regularly elliptical in form. Metopidium well 

 rounded in both diameters with a slight median carina; apex 

 rather slender and acute, sometimes a little decurved. Color 

 pale testaceous brown tinged with ferruginous on the head, an- 

 terior margin of the metopidium, and over the humeral angles; 

 anterior oblique vitta generally distinguishable above, distinct 

 below the middle where it connects with the elongated vertical 

 median spot which is nearly hyaline; behind the oblique vitta 

 the surface is dark brown ; the posterior vitta sometimes merged 

 in a pale tip. Elytra hyaline with a punctured blackish base 

 and an elongated fuscous tip. Tergum black with a broad 

 white band at the base which shows through the elytra. Head 

 broad triangular, finely punctured; margins of the cheeks, 

 lorse and clypeus jointly rectilinear or nearly so. Beneath and 

 legs pale brown. Length 8-9 mm. 



Fairmaire's description answers excellently to individuals 

 of this species in which the anterior vitta is obsolete above the 

 junction of this vitta with the median spot. It then forms an 

 angled transverse band as described by him. This is the lar- 

 gest species of Cyrtolobus known to me. I took several ex- 

 amples at Atlanta, Ga. , in May 1899, and in the Cornell Uni- 

 versity collection is a specimen taken at Ithaca, N. Y. 



6. Cyrtolobus grandis n. sp. PI. 2, fig. 17. 



Large, elongated, suggesting a small Smz'lia camelus. Dorsal crest 

 nearly semi -circular in outline, beginning a little before the humeri, almost 

 up to the front of the metopidium ; behind sloping away to the slender and 

 acute posterior process which very nearly attains the apex of the elytral 

 areoles in the female. Color pale ferruginous or testaceous yellow, very 

 coarsely punctured. Anterior pale vitta broad and diffuse anteriorly at base,
