regularly tapering from the eyes forward, lm-

 transverse wrinkles. Pronotum and scutellum 

 with the small punctures in irregular transverse 

 rows between the much broader, broken trans- 

 verse ruga?. Elytra sub-alutaceous, evenly, 

 sparsely and very finely punctate. Under sur- 

 face finely and sparsely punctate. Genital plate 

 of male widely and very deeply emarginate or 

 bi-lobed, each lobe with its inner margin deflexed 

 and apex obtusely rounded. Length, 21 — 23 

 mm.; width, 12 — 14 mm. (Fig. 30). 



Dunedin, Miami and Key West, Fla., 

 Nov. 30 — April 1. About a dozen specimens have been taken 

 at Dunedin. They were swept singly from foliage along the 

 margins of orange groves and cultivated grounds. Known only 

 from Florida, the type from Crescent City and the other half 

 dozen recorded stations ranging from Jacksonville to Big Pine 

 Key. It is one of the largest and most handsome of our eastern 

 Pentatomids.

 head broad, triangular, strongly deflexed; cheeks with side 

 margins elevated and thickened, their tips not reaching that of 

 tylus; beak stout, reaching middle of hind coxse, its second 

 joint as long as third and fourth united ; pronotum short and 

 wide, with both front angles and humeri obtusely rounded, its 

 disk almost smooth, with front portion feebly declivent ; scutel- 

 lum elongate, strongly tapering, its tip narrowly rounded, frena 

 reaching its apical fourth ; membrane surpassing abdomen, its 

 veins simple ; connexivum narrowly exposed ; tibise sulcate 

 above only on apical half ; osteolar opening very small, without 

 auricle or canal. Genital plate of male short, wide, its hind

 territory.
