Vol. VIII] VAN DUZEE— NEW SPECIES HEMIPTERA 295 



fuliginous with a large fuscous cloud centered at the apex of the areoles. 

 Base of the anterior coxae, much of the posterior, and base of the tarsi 

 whitish. 



Described from one female example collected by Mr. Otto 

 Heidemann at Rock Creek, D. C, June 20, 1890, and deter- 

 mined by him as "Pilophorus Icctus Uhl." I took one male at 

 Washington, D. C, June 25, 1905, and a female at Woodbine, 

 N. J., August 21, 1902, but both are now too imperfect to be 

 used as types. 



Holotype in collection of the author. 



The following key will distinguish our recorded North 

 American species of Pilophorus: 



Third antennal segment with the apical one third abruptly clavate; 

 posterior silvery line interrupted on the corium, not dislocated at 

 claval suture ; length 3>^ mm Icetus, new species 



Third antennal segment gradually thickened toward the apex or nearly 



linear \ 



1. Third antennal segment linear or practically so; posterior silvery 



line entire, a little oblique; length 4 mm discretus, new species 



-. Third antennal segment obviously thicker at apex 2 



2. Third antennal segment but little thickened at apex 3 



-. Third antennal segment much thickened at apex, clavate; apex of 



elytra smooth ; length 5 to 6 mm 5 



3. Surface clothed with rather long appressed grey hairs 4 



-. Surface smooth or with scattering stiff hairs; apex of corium pol- 

 ished exterior to cubital vein only; posterior silvery line dislo- 

 cated 5 



4. Apex of corium polished across its whole width ; posterior silvery 



hne dislocated at the clavus schwarzi Reut. 



-. Apex of corium polished exterior to cubital vein only; posterior 

 silvery line entire tomentosiis, new species 



5. Length about 3,^ mm. ; basal segment of rostrum scarcely surpassing 



the bucculas ; base of fourth antennal segment broadly pale 



walshi Uhl. 



-. Length 5 mm. ; basal segment of rostrum nearly attaining base of 



head ; base of fourth antennal segment very narrowly pale 



clavatus Linn. 



6. Elytra comparatively broad, but little widened apically ; hind tibiae 



normal; fourth antennal segment white with apex black 



ciiinamopterus Kb. 



-. Elytra more expanded apically; hind tibise flattened and more or less 



curved 7 



7. Third antennal segment white; base of vertex scarcely elevated, its 



median line sulcate amoeiius Uhl. 



-. Third antennal segment fuscous or black 8 



8. Base of vertex sulcate ; membrane with a blackish lunule at apex of 



the areoles ; elytra clothed with short, stiff, erect hairs 



crassipes, new species 



-. Base of vertex not sulcate ; membrane with a large blackish cloud 

 covering the larger areole and invading the surface beyond ; elytra 

 smooth tibialis, new species
