This species is a Cyclophylla of Selys. It falls next to Gomphoides 

 volsella Calvert, in the Synopsis of Mexican and Central American 

 species in Biol. Centr. Araer. Neuropt., p. 154. It differs from 

 volsella in the shape of the appendages ; and in the anterior green ante- 

 humeral stripe being narrower, not reaching to the antealar sinus nor 

 confluent with the second or posterior green antehumeral stripe supe- 

 riorly (as is the case in volsella').

 (Plate VII, figs. 126, 126J.) 



cT. Head bluish-green ; basal parts of labium, extreme free edges of 

 labrum and of nasus, and external surfaces of mandibles yellow ; 

 ocellar area brown ; superior surface of frons nearly horizontal, not 

 declined ; hind margin of occiput nearly straight, with black hairs. 



Prothorax green ; hind lobe and some marks on the middle lobe 

 blackish-brown. 



Thoracic dorsum rich chocolate-brown, the following yellow : an 

 antehumeral stripe of almost uniform width (.8 mm.) about as far 

 from the mid-dorsal carina as its own width and almost parallel 

 thereto, being only a little nearer to the carina at its upper than its 

 lower end, confluent below with a transverse yellow stripe ("collier 

 mesothoracique "), which latter is interrupted at the lower end of the 

 median carina ; a fine green line on all but the upper end of the 

 humeral suture ; a slightly wider green line a short distance in front of, 

 and parallel to, the humeral suture for the whole height of the sclerite. 



Anterior edge of the mesepimeron with a brown line or narrow stripe 

 about equal in width to the brown, which separates the just-mentioned 

 humeral and antehumeral lines, but all the remainder of the 7nesepimer- 

 011 and all the metapleitron yellowish-green, without darker markings of 

 any kind. Pectus yellowish. 



Abdominal segments 2-7 greenish-yellow mid-dorsally for the entire 

 length of each segment, except at the intersegmental articulations, 

 but narrowing posteriorly on each (in some to a mere line) ; sides 

 superiorly blackish -brown behind the greenish auricles on 2, for the
