640 FAMILY XXIV. — ANTHOCORID,£. 



d. Basal margin of pronotum very deeply sinuate or concave; disk 



of pronotum with a distinct transverse groove. 



e. Pronotum with transverse median groove confined to the disk, 



its hind lobe without a median longitudinal sulcus; clavus 



very feebly if <it all punctate; osteolar channel very long, its 



sides merging to form a carina which curves outward to the 



metapleural submarginal ridge. III. Cardiastethus, p. 642. 



ee. Pronotum with transverse median groove reaching across disk 



onto the sides, its hind lobe with a short longitudinal sulcus 



in front; clavus distinctly coarsely punctate; osteolar channel 



long, curved backward. IV. Poronotus, p. 643. 



dd. Basal margin of pronotum more widely, less deeply sinuate or 



concave; disk of pronotum without a transverse groove, but 



with a distinct median longitudinal one; joint 1 of antennae 



scarcely reaching tip of tylus. V. Dufouriellus, p. 644. 



aa. Front and hind femora swollen, the former dentate beneath. 



VI. Scoloposcelis, p. 645. 



I. Brachysteles Mulsant & Rey, 1852, 104. 



Small oval pubescent species having the head scarcely longer 

 than the width at base of vertex, but slightly prolonged in 

 front of bases of antennae; eyes prominent; ocelli widely sepa- 

 rated ; beak reaching apex of prosternum, its first joint not 

 reaching front of eyes ; antenna? as long as head and pronotum 

 united, joint 1 slightly surpassing tip of tylus, 2 not longer 

 than width of head across eyes, 3 and 4 subequal, subfusiform, 

 together slightly longer than 2; pronotum with sides in front 

 of middle flattened, but little narrowed, acutely margined and 

 without a distinct collar; elytra entire, in our species surpass- 

 ing tip of abdomen, rather densely, finely but distinctly punc- 

 tate ; osteolar opening without a distinct channel, but with a 

 long, obtusely curved carina. One of the six known species 

 has been recorded from our territory. 



617 (866). Brachysteles pallidus Reuter, 1884, 118. 



Color a nearly uniform pale clay-yellow; front and hind margins of 

 pronotum and tip of scutellum often tinged with fuscous; membrane pale 

 hyaline. Pronotum more than twice as wide at base as long, sides 

 straight, apex about one-fourth narrower than base, disk behind calli 

 finely, densely and distinctly punctate. Base of scutellum convex, obso- 

 letely punctate. Length, 1.5 — 1.7 mm. 



A West Indian species, recorded by Uhler (1886, 21) from 

 the "Southern States," this being the only mention from this 

 country.
