SUBFAMILY III. — ORTHOTYLIN^E. 819 



paler; under surface piceous, shining. Head minutely granulate, vertex 

 with a narrow impressed longitudinal line. Basal half of pronotum 

 vaguely transversely rugose. Mesoscutum strongly convex, smooth, shin- 

 ing. Elytra almost smooth. Length, 6.5 — 7.5 mm. 



Scarce throughout Indiana, May 12 — July 11; beaten from 

 oak and swept from herbage along margins of woodland. 

 Ranges from Ontario and New England west to Michigan and 

 Illinois and southwest to North Carolina. The records of its 

 occurrence are remarkably few, taking into consideration its 

 rather wide distribution, peculiar form and coloration. Breeds 

 on the yellow and white oaks, Quercus muhlenbergia Engl, and 

 Q. alba L., and occasionally on ash. In teneral specimens the 

 general color is brownish with basal half of pronotum some- 

 times reddish as in regalis, but scutellum always in part whitish. 



871 (1159). Pseudoxenetus regalis (Uhler), 1890, 80. 



Differs from scutellatus mainly by the characters given in key, the 

 basal half of pronotum and the mesoscutum being reddish or reddish- 

 yellow, as are also the pro- and mesosterna and sometimes the lower part 

 of head; white bar at base of cuneus more often wanting; antennae black- 

 ish to fuscous, basal half of joint 3 pale; legs piceous-brown, the tibiae 

 somewhat paler. Length, 7 — 7.5 mm. 



Sarasota and Dunedin, Fla., Jan. 28 — April 1 ; beaten from 

 its host plant, the live oak, Quercus virginiana Mill., recorded also 

 from Bellaire and Jacksonville, Fla. Long Island, N. Y., June 

 20 (Davis) . Ranges from New York and central Illinois, south- 

 west to Florida and Texas. Uhler mentions it as occurring in 

 Pennsylvania on the white-heart hickory, Hicoria alba (L.). 

 It is very probable that a large series from all parts of the 

 country will show that this and the preceding are but color 

 forms of the same species, in which case the name regalis will 

 have precedence, and our more common northern form will be 

 known as P. regalis scutellatus (Uhl.). The Davis specimen, 

 identified by Knight as regalis, has the apical half of scutellum 

 white, basal half of pronotum red. 



Tribe V. CERATOCAPSINI Van Duzee, 1916a, 211. 



To this tribe, as characterized in the key, p. 796, belong two 

 of our eastern genera.

 behind middle, basal half of disk strongly convex; embolar margins 

 sinuate on basal half. I. Pamillia.
