been a misfit in the genus Cyrtolobus and rendered that genus hard to define. » Ball distinguishes the 

 genus Grandolobus as foUows : 



« Resembling Smilia in general size and form but with the crest shorter and farther back 

 from the metopidium. the apical process of the pronotum long and slender as in Cyrtolobiis. 



» Face broader than in Smilia, as broad as in Cyrtolobus, the metopidium broader and round- 

 ing over above as seen from the front rather than triangular as in Smilia. Pronotum, as scen 

 from side, long and slender with a rather short high, foliaceous crest arising just back of the line 

 of the metopidium in a fairly symmetrical arch a Httle longer than its height. This crest occupies 

 a little over half of the length of the pronotum arising with a slight sinuation in front and 

 with an obtuse angle behind. There is a major inflation in the middle and a minor one near 

 the posterior angle. The elytra are long and narrow with typical Cyrtolobus venation, the apical 

 cell small, ahnost round with a long pedicel. »

Geographical distpjbution : The single species assigned to this genus was described from 

 Arizona, but incequalis Fowler, from Mexico, seems to be a synonym.

Characteps : One of the largest and most wide-spread of any of the membracid genera in North 

 America, which area seems to be its center of distribution. The insects of this genus are small, rather 

 inconspicuous, with elongate bodies and regularly arcuate, slightly flattened pronotums, and are usually 

 tree-inhabiting. The genus may be rather easily recognized by the following characters ; Head sub- 

 triangular; base weakly arcuate; eyes ovate, wider than high; ocelli prominent, equidistant from each 

 other and from the eyes and situated slightly below a line drawn through centers of eyes; inferior mar- 

 gins of genae sinuate; clypeus weakly trilobed, extending for half its length below inferior margins of 

 gente. Pronotum moderately elevated, laterally compressed, arcuate, highest at middle; punctate but 

 with no lateral ridges; metopidium sloping, wider than high ; median carina strongly percurrent; humer- 

 al angles weak and rounded; posterior apex of pronotum gradually narrowed to an acute point which 

 extendsbeyond internal angles of tegraina but does not reach the tips. Tegmina largely free, only a 

 small part of the corium being covered b}' the sides of the pronotum; hyaline or clouded ; corium with 

 three prominent longitudinal veins of which the inner pair is connected by a cross-vein ; five apical and 

 two discoidal cells ; median apical cell petiolate ; apical limbus broad. Legs simple ; all tarsi about equal 

 in length.

Geographical dlstribution : This is distinctly a North American genus with representatives 

 in all parts of the United States and with species in Canada and in Mexico. The localities given for the 

 following species are roughly grouped according to areas. Where a species has been reported from only 

 one state, that state is mentioned. The designation « United States » indicates that the species is found 

 in practically all parts of the countrjf.
