Jan., 1922 synopsis or the genus stenocranus 75 



Length of body, female, 3 mm.; male, 2.75 mm.; length to tip of 

 elytra, female, 5 mm.; male 4.25 mm. 



Redescribed from a large series of males and females col- 

 lected in Mississippi by the writer at Aberdeen, June 26, 1921, 

 Columbus, June 23, 1921; Tupelo, July 2, 1921; Fulton, July 4, 

 1921; and Rokeena, July 20, 1921; and two females taken at 

 Clemson College, S. C, by G. G. Aineslie. These were all 

 swept in abundance from cane-brake and the only definitely 

 known host plant is the bamboo-cane, Arundinaria tecta. 



Stenocranus palactus Van D. 

 (1897 Bui. Buf. Soc. Nat. Sci., v, p. 232). 



Form and size of dorsalis. Distinguished by its long vertex 

 and large, foliaceous tibial spur and banded frons. 



Head decidedly narrower than pronotum. Vertex extended half 

 its length beyond the eyes, carinae prominent except median one, which 

 is faint. First antennal segment a little shorter than the second. 

 Pronotum slightly shorter than the vertex, strongly tricarinate, the 

 lateral carinas attaining the hind margin. Scutellum one and a half 

 times as long as pronotum, tricarinate, the lateral carinte rather indis- 

 tinct. Calcar unusually large and foliaceous. 



Color is fulvous yellow above, paler beneath. Frontal fovse inter- 

 ruptedly black over the apex of the head from the base of the antennas 

 to the middle of the vertex; front crossed by a brown band below the 

 antennae, and another crossing the base of the clypeus and extending 

 over the anterior coxas and pleural pieces; apex of front and its median 

 carina interruptedly pale. Antennas somewhat fuscous. Eyes black. 

 Elytra subhyaline, nervures yellowish, the commisural white with a 

 brown line before the apex of the clavus ; inner sector of the corium and 

 the apical nervures, except the base of the two outer, fuscous; a smoky 

 cloud covers the anastomosis at the base of the middle apical areole 

 and spreads feebly over the inner area of the membrane. Tergum 

 brownish. Legs pale, femora lineated and the tibiae banded with 

 fuscous. 



Female genitalia typical. Male pygofer trilobate, middle lobe with 

 a somewhat semicircular median notch, each side of which is extended 

 tooth-like; lateral lobes, genital styles, and anal style dark fuscous; 

 anal tube without ventral processes. 



Male slightly smaller than female, with slightly shorter vertex; 

 otherwise similar in appearance. 



Length of body, male, 2.75 mm. ; female, 3.50 mm. ; length to tip of 

 elytra, male, 4 mm. ; female, 4.9 mm.
