TRIBE III. — PHYSATOCHEILINI. 487 



IV. Tingis Fabricius, 1803, 124. 



Small elongate-oval species distinguished as in generic key 

 and having the bucculae closed in front ; head with five rather 

 slender spines; beak reaching beyond middle coxae; pronotum 

 coarsely punctate, tricarinate, the carina parallel, each with 

 a single row of very small cells ; elytra surpassing apex of 

 abdomen, all the cells very small, discoidal areas very long, 

 reaching their apical fourth, their marginal nervures strongly 

 elevated ; costal area with three rows of cells, subcostal area 

 with two to three rows. The genus is represented in this coun- 

 try by a single known species. 



455 ( — ). Tingis necopina (Drake), 1919, 420. 



Elongate-oval, narrowed behind. Above pale yellowish-brown,, the 

 veinlets with a few darker markings ; head and sides of apical third of 

 pronotum, blackish; spines of head whitish; under surface reddish-brown, 

 the prosternum, coxae, trochanters and femora darker; sides of rostral 

 groove and tarsi tinged with yellow. Joints 1 and 2 of antenna? dark 

 brown, 1 thicker and slightly longer than 2; 3 pale brown, two and three- 

 fifth times the length of 4, more slender than 2; 4 blackish, slightly 

 enlarged toward tip. Length, 3.1 mm. 



Known only by a single specimen in the Uhler collection, 

 taken at Bladensburg, Md., July 27, 1890. 



V. Teleonemia Costa, 1864, 144. 



Elongate, narrow subparallel species having the head usually 

 with five short spines ; antennae cylindrical, contiguous at base, 

 joints variable as to species; pronotum tricarinate, the anterior 

 third narrower, middle third much wider and strongly convex, 

 posterior prolongation elongate-triangular, its tip subacute, 

 paranota very narrow, usually reflexed against the sides of 

 disk; elytra much surpassing abdomen, subparallel to middle, 

 feebly constricted at apical third, their tips broadly rounded ; 

 discoidal areas extending beyond the middle. The genus is 

 best represented in Central America and Mexico, where 14 

 species are known. Nine occur in North America, six in the 

 southern states.
