TWO NEW SPECIES OF REDUVIIDAE FROM THE 

 UNITED STATES (HEM.). 



H. G. BARBER, Rose/le, N. J. 

 Alloeorrhynchus Fieb. 



The genus Alloeorrhynchus almost world-wide in its distri- 

 bution has three representatives in the neotropical realm. No 

 member of the genus has hitherto been reported from within 

 the United States, although a closely related genus Phorticus is 

 represented in Texas. Members of the genus Alloeorrhynchus 

 can be differentiated by the unkeeled ventral base of the 

 abdomen; shining body; longer basal segment of the antenna 

 and by the character of the fore and intermediate femora which 

 are angularly dilated or toothed beneath near the middle and 

 finely denticulate from thence to apex. The anterior tibiae are 

 inwardly widened at apex and provided with spongy fossa. 



Alloeorhynchus nigrolobus, n. sp. 



Flavo-testaceous, sparsely pilose. Head, posterior lobe of pronotum, scutel- 

 lum, meso- and metasternum nigro-piceous; apical part of corium and antennae 

 except basal segment infuscated. Scutellum and metapleura dull; corium, 

 membrane and remaining parts shining. First segment of antenna pale 

 clavate, the remainder of the antenna embrowned, more densely pilose, second 

 segment fully twice as long as first segment. Rostrum pale testaceous, second 

 segment as long as third and fourth taken together. Anterior lobe of pronotum 

 bright yellow verging into orange, over twice as long and nearly two-thirds 

 as wide as posterior lobe. Legs entirely pale testaceous; fore femora angularly 

 dilated forming a stout tooth about middle and furnished with minute black 

 spines from thence to apex; fore tibia finely spinulose, abruptly expanded 

 within on its apical third and furnished with spongy fossa along its obliquely 

 truncated apex. Less incrassate intermediate femora widest across the middle 

 point and there armed beneath with two acute black spines, from thence to 

 apex with minute black spinules; inner face of intermediate tibia very finely 

 serrate. Scutellum dull black, provided outwardly with few long hairs. Entire 

 corium and clavus very shining, finely and sparsely pilose. Membrane less 

 shining, irridescent, translucent, somewhat ' lacteous. Connexivum pale 

 flavo-testaceous exposed beyond middle point of hemielytra. Venter shiniiiL', 

 sparsely pilose, somewhat embrowned towards apex.
