250 - THE CANADIAN ENTOMoLOGIST. 



New York and Ottawa, Ont. It appears to be subject to very little 



variation. 



Thamiiotettix lurida n. sp. 



Form of T. subcenea ; pale yellow marked with fulvous ; elytra deep 

 fulvous, with a whitish commissural spot. Length 5 mm. 



Vertex but little longer at the middle than next the eye ; surface 

 covered with deep oblique rugae which emit the broad margins and 

 medial line, and near the hind margin, on either side, is a minutely 

 punctured area. Pronotum transversely wrinkled. Face fulvous ; a large 

 spot on the apex of the front and four or five lateral transverse arcs, pale 

 yellow. Vertex and pronotum pale yellowish ; the former with a trans- 

 verse band connecting the ocelli ; the latter, with the lateral angles and 

 four more or less distinct longitudinal bands, fulvous. Scutellum pale, 

 with the basal angles and two small spots between them fulvous. Elytra 

 deep fulvous, opaque, especially on the clavus and base of the corium. 

 A large commissural spot near the apex of the clavus, and some smaller, 

 indistinct ones on the discal areoles of the corium whitish. Abdomen 

 and all beneath deep fulvous $ , or blackish $ ; the pleural pieces and 

 connexivum edged with pale ; legs and genitalia of the ^ fulvous. 



Described from two examples, a ^ received from Prof. Osborn, 

 labelled "Ames, Iowa, May 19th, 1881," and a % from Mr. G. C. Davis 

 labelled "Agricultural College, Mich., Oct. 24th, 1888." 



This pretty little insect is very near my T. subcenea from California, 

 but it is broader and shorter ; the vertex is not so long as in that species, 

 and with the pronotum is distinctly wrinkled ; the elytra are deeper 

 coloured and almost opaque ; the valve of the ^ is produced medially in 

 a short blunt tooth, and the plates are broader, especially toward their 

 slightly divergent tips, and are less heavily fringed. In the $ the central 

 tooth on the hind margin of the last ventral segment is narrower and 

 more acute than in its ally. 



T. subcenea and lurida are characteristic of neither this genus nor 

 Athysanus, to either of which they might be referred. Genus Phlepsius 

 could, perhaps, be modified so as to include them, as they want only the 

 elytral reticulations of being very good Phlepsiids. From Scaphoideus 

 they are debarred by their shorter antennal setse and broader form. For 

 a note on this genus see Entomologica Americana, Vol. VI., p. 52.
