collection of the Boston Society of Natural History, the last 

 two kindly sent me for study by Mr. H. C. Parshley, and a 

 male taken at Stowe, Vt., July 4, by G. P. Engelhardt. This 

 is a large, clearly marked species and may be known by the 

 black lateral margins of the pronotum and conspicuous cru- 

 ciate black markings on the elytra.

28. Orthotylus lateralis, new species. 



A little larger and broader than hrunneus; pronotum pale 

 with the lateral margins broadly black. Length Ayimm. to 

 the tip of the membrane. 



Head more oblique than in dorsalis and its allies. Vertex 

 fiat, the foveate depression rather obscure and the basal carina 

 feeble. Front convex, polished, the clypeus small and promi- 

 nent. Eyes very large, in the female as wide as the vertex, 

 wider in the male; when viewed from the side, ovate, reach- 

 ing to the gula and but little surpassed by the apex of the 

 head. Pronotum long and much narrowed anteriorly, the sides 

 very slightly arcuated, the anterior angles subacute ; callosities 

 very small and placed close to the anterior margin, leaving the 

 impressed bounding line behind them at about the anterior one- 

 third of the pronotum; hind margin a little concave, leaving 

 the basal lobe of the scutellum broadly exposed. Elytra broader 

 than in hrunneus, about as in modestus, nearly parallel, the 

 apex of the abdomen reaching the middle of the cuneus in the 

 male and its apex in the female. 



Male genitalia prominent; dextral hook long, pennate, the 

 ventral edge smooth, the dorsal "feathered" or flattened and 

 serrated on the apical half, tapering to an acute point ; sinistral 

 long, nearly straight, toward its apex triangularly widened 

 and armed within with a stout tooth. 



Color fuscous-brown ; head at base and below becoming 

 pale yellowish. Antennae black. Pronotum pale yellowish, the 

 sides broadly black both above and below. Basal lobe of the 

 scutellum fulvous, apical pale yellowish. Clavus blackish-
