20 THE CANADIAN ENTOMOLOGIST. 



Described from one specimen, Isthmus of Tehuantepec, Mexico, F. 

 Sumichrist. 



This is the first of the genus described from North America, and is 

 very closely related to S. negledus, H. S. 



It is at once distinguished from that species, however, by a more 

 robust form, a different antennal and abdominal coloration, and by the 

 membrane not quite reaching the tip of the abdomen. 



FAMILY TINGITID^. 



Cantacader, A. & S. 



Gen. char. — Head elongated and projecting but little between the 

 antennae ; front horned ; eyes small, globular, not prominent ; antennae 

 slender, very long ; the first two joints short, second very long, fourth 

 short, pointed fusiform ; beak lying in a well pronounced groove, and 

 reaching nearly to the base of the posterior legs ; prothorax somewhat 

 abruptly rounded at its posterior border and not prolonged to a point,

 abdomen : head brownish on vertex with three pale horns, two just back 

 of antennte and the third in the centre just back of these, with their points 

 converging forward towards each other, two pale but prominent lateral 

 carina, one on each side, extending from base of antennae back to pro-

 thorax with lateral margins reflexed, and with three prominent carina ; 

 wings long with the raised veins piceous and the reticulated cells small ; 

 abdomen and legs brownish yellow, with the extreme tips of tibiae and

Described from one specimen sent me by Mr. Samuel Henshaw, 

 labelled Boston, July 7th, 1879, to whom I _take pleasure in dedicating 

 the species. 



It is the only species of the genus described from North America, and 

 is a very easily recognized species.
