median carina; posterior angles obtusely rounded; lateral carinae strongly 

 divergent cephalad. Abdomen slightly longer than thorax, beyond first 

 segment ovate-lanceolate; membranous margins of first and second seg- 

 ments brownish; tergum of first abdominal segment coarsely longitudi- 

 nally rugose, a third longer than wide, sides nearly parallel; tergum of 

 second segment wider posteriorly, and three-fourths length of first, sud- 

 denly narrowed to the basal suture, where it is narrower than the first, 

 coarsely longitudinally rugose; remaining segments smooth and shining; 

 ovipositor dark brown ; posterior tibial spines not one-half length first 

 tarsal joint. The male differs only in size. 



Described from seven females and three males reared from

CHARACTERS OF A NEW SPECIES OF THELIA. 



By E. P. Van Duzee, Buffalo, N. Y. 

 In looking over my material of Thelia univittata a year or two 

 ago I found I had confused two distinct species under this name, 

 one of which appears to be still undescribed. Later I sent an 

 example of the new form to Dr. F. W. Coding, who was then 

 preparing a catalogue of the North American Membracidae, and 

 he pronounced it identical with some material he had placed 

 under Thelia cratcegi. In fact, the female does have a stronger 

 resemblance to the female of cratcsgi than to that of univittata, 

 but the specimen I have placed as the male of this new species 

 is very close to the male of univittata, and not at all like that of 

 cratczgi. Below is a comparitive description of this new form : 



Thelia godingi n. sp. — In Bull. Buffalo Society of Nat. Sciences, v, p. 

 189, 1894. Female; shorter and stouter than in univittata with the pro- 

 notum more thickly and evenly punctured and extended to or beyond the 

 tip of the elytral areoles. In univittata the punctures are coarser and 

 more irregular, leaving a few scattering callous-like spots and about four 

 longitudinal smooth lines, beginning a little behmd the shoulders and 

 becoming connivent or evanescent before the tip, which in this species is 

 more slender than in godingi and does not attain the apex of the elytral 

 areoles. These longitudinal lines are more obscure and irregular in 

 craiczgi, and scarcely or not at all discernible in godingi. In this latter 

 species the dorsal hump is nearly vertical before and behind, as wide 

 above as below, with the apex well rounded and showing a slight inclina- 

 tion to become pointed at the middle. In cratcegi the edges of the hump 

 are parallel, but the anterior apical angle is rounded off, and the posterior 

 is subacute. In univittata this protruberance is proportionately longer 

 and more slender, and quite distinctly inclined forward with its apex
