TRIBE III. — PHYSATOCHEILINI. 485 



the veins of costal area pale fuscous-brown; femora each with a broad, 

 vague median brownish ring; mesosternum and tarsi fuscous. Joints 

 1 — 3 of antennae dull yellow, 3 about four times as long as 1 and 2 

 united, its apical fourth feebly but visibly thickened, female, distinctly 

 so, male; joint 4 fusiform, paler at base, slightly longer than 1 and 2 

 united. Cells of paranota coarse, their margins rugose. Discoidal area 

 of elytra reaching almost to apex of abdomen, its outer margin sinuate; 

 costal area with two or three confused rows of rather large subhyaline 

 cells. Length, 4.5 — 4.7 mm. 



Normal, 111., May 10 (III. Nat. Hist. Surv. Coll.) . Described 

 from Illinois. Known also from Maryland, Virginia and the 

 District of Columbia. 



452 (665%). Physatocheila variegata Parshley, 1917a, 166. 



Elongate-oval. Pale grayish-brown variegated with fuscous; spines 

 of hood and ends of carinas dull yellow; reflexed paranota, discoidal areas 

 and veins of costal margin more or less fuscous-brown; antennae and legs 

 pale reddish-brown, the fourth antennal darker; under surface dull yel- 

 lowish-brown, sparsely clothed with very short and fine yellow scale-like 

 hairs. First antennal stouter but scarcely longer than second, third 

 more slender than in plexa. Paranota less densely punctate than there. 

 Costal area with two or three confused rows of cells. Length, 3.3 — 4 mm. 



Jackson Co., Ind., May 20 (W. S.B.). Natick, Mass. (Frost). 

 Hewitt, N. J., July (Davis). Ranges from New England 

 west to Vernon, B. C, and south to West Virginia. Occurs on 

 white pine. Osborn & Drake regard this form as the plexa of 

 Say, but Van Duzee and Parshley disagree with them. As 

 Say's brief description will fit both species and his type is 

 destroyed, the question must remain unsettled. 



II. DlCHOCYSTA Champion, 1898, 33. 



Small elongate narrow species having the head armed with 

 five, rather long decumbent spines ; beak reaching first ventral ; 

 sternal groove uninterrupted ; antennae with joints 1 and 2 very 

 short, stout, 3 more slender, longer than the others united, 4 

 fusiform ; pronotum tricarinate, paranota as in key ; elytra 

 with sides subparallel, tips rounded, extending beyond tip of 

 abdomen ; discoidal area large, triangular, surpassing middle, 

 its sides elevated. One species is known. 



453 (670). Dichocysta pictipes Champion, 1898, 34. 



Elongate, subparallel. Dull brownish-yellow; fourth antennal, bulbs 

 of paranota and cross veins of costal area, in great part or wholly fus- 

 cous; elytra with a few small scattered fuscous dots; joints 1 — 3 of 

 antennae and legs brownish-yellow; femora and tibia? with one or two
