HEMIPTERA OF LOWER CALIFORNIA. 287 



coarse grains, the posterior lobe thick and wide, coarselj' 

 and unevenly wrinkled in several separate divisions, the 

 divaricating lines almost obsolete ; the lateral border thick, 

 broadly curved, coarsely tuberculated below the slender, 

 waved carina, the humeral tubercle long, tumid, absorb- 

 ing the lateral carina; posterior margin almost straight 

 and abruptly steep against the base of scutellum, each 

 side of this obliquely curved. Scutellum coarsely knobbed 

 at base, more finely towards the tip, deeply scooped 

 out, the apical portion narrow, subcylindrical, ending in 

 a knoblike tip. Corium minutely scabrous, and the cla- 

 vus more coarsely so. Abdomen long ovate, wider than 

 the wing-covers, but not broadly expanded, with the 

 margin bright red all around; venter highly polished, 

 transversely wrinkled. 



Length to tip of venter, 35 mm. Width of pronotum, 

 8)4 mm. 



Only one specimen, a male, has thus far been brought 

 to my notice. It was kindly given to me by Dr. George 

 H. Horn, as having been taken in Lower California. It 

 differs from all species known to me b}' having the outer 

 edge of the connexivum thickened, not sharp-edged, as 

 is common to the large Mexican forms. 



Stenopoda culiciformis Fab. Specimens were cap- 

 tured at Cape St. Lucas by Mr. John Xanthus. 



Emesa longipes DeGeer. Several specimens of this 

 insect were secured at San Jose del Cabo by Dr. Gustav 

 Eisen. After careful comparison of several specimens 

 with my types from the eastern United States, I can find 

 no important differences to separate them. 



Specimens were secured also at Cape St. Lucas by 

 Mr. John Xanthus.
