1066 FAMILY XL. — CORIXID^E. 



I. Callicorixa White, 1873, 62. 



The principal characters distinguishing this genus are given 

 in the key. Two species have been recorded from the eastern 

 states. 



KEY TO EASTERN SPECIES OF CALLICORIXA. 



a. Elytra glabrous, distinctly rastrate over the entire surface; pale 

 lineations of elytra nearly straight and transverse throughout. 



1204. PR^EUSTA. 



au. Elytra thickly pubescent, minutely punctate, the clavus alone very 



finely obsoletely rastrate; pale lineations of elytra irregularly 



vermiculate, becoming transverse and straight only on base of 



clavus. 1205. kollarii. 



1204 (1416). Callicorixa pr^usta (Fieber), 1848, 521; 1851a, 28. 

 Pale fuscous with yellowish lines; head yellowish, tylus rufo-f uscous ; 



pronotum with seven or eight narrow blackish cross-bars ; pale lines of 

 elytra, including membrane, transverse, undulated, subparallel, often 

 abbreviated; dorsum, meso- and metasterna, xyphus and prosternal lobes, 

 black; embolium pale, darker at base; legs pale, base of front femora and 

 upper face of tibiae with oblong blackish spots. Frontal impression of 

 male oblong, reaching middle of eyes. Palae and pegs as in fig. 16. 

 Length, 6.7 mm. 



Hendon and Nazeing, England, April 2 — July 6 (British Mas. 

 Coll.). A palsearctic species, recorded in this country from 

 Canada, New England, Michigan and Alaska. The northern 

 lecords of C. kollarii probably belong here. 



1205 (1417). Callicorixa kollarii (Fieber), 1851a, 17. 



Oblong, robust. Pale fuscous, shining; head yellow; pronotum obso- 

 letely rastrate, not carinate, with six or seven transverse fuscous lines, 

 these narrower than the alternate pale spaces; elytra blackish-fuscous, 

 closely marked with short, irregular, undulate transverse pale lines; 

 embolium sordid-white; legs wholly pale. Male with frontal impression 

 oval, deep, very large; front tibiae acutely, triangularly dilated; pala sub- 

 semicircular, acute. Length, 6.5—6.7 mm. 



Antigua, West Indies (British Mus. Coll.). Described from 

 Brazil and Cuba and recorded by Uhler (1894a, 224) under the 

 name Corisa cubce (nee. Guerin) from Florida. The northern 

 records given by Kirkaldy, Bueno and others probably belong 

 to prceusta. 



II. Cymatia Flor, 1860, 783. 



Head with eyes broader than pronotum; vertex horizontal, 

 projecting between the eyes, with a more or less distinct 

 carina; front feebly concave, male, fiat, female; pronotum 

 broader than long, the front half with a median carina ; pala
