Conocephalus Modes ^" new species (PI. XXI, tig. 6; XXII, 5 and 23; 

 XXIII, 12 and 13; XXIV, 5.) 



This insect with C. graciUinms and C. insularis forms a group 

 (E) of the subgenus Xiphidion agreeing in the slender form, 

 broad convex callosity of the lateral lobes of the pronotum, elon- 

 gate male tegminal tympanum and distinctive color pattern. The 

 present species resembles insularis somewhat the more nearly, 

 agreeing with that species in the form of the vertex, but having 

 the ventro-cephalic angle of the lateral lobes of the pronotum 

 less pronounced (as in graciUimus). The coloration of iriodes is 

 normally much more intense than in either of the above species, 

 the tympanum of the male tegmina even more elongate, while the 

 male cerci are very different, showing a distinct resemblance to 

 the similar but more decidedly specialized type found in the 

 otherwise different and distinctive C. angusiijrons.

Description of Type. — Size medium, form slender, coloration distinctive. 

 Head with dorsum of vertex, when seen from lateral aspect, weakly but distinctly 

 ascending above the plane of the occiput (much as in insularis). Fastigium 

 of vertex approximately two-thirds the width of basal antennal joint, narrow- 

 ing with a distinct concavity to facial suture, when seen from front api)rox- 

 imately twice as deep as wide. Eyes moderately large, not imusually pro- 

 truding. Lat(>ral lobes of jjronolum vertical, cephalic margin broadly convex 

 to the ventro-caudal angle which is very sharjjly rounded, caudal margin weakly 

 convex to the broad and shallow hunicral sinus, convex callositj^ very broad. 

 Tegmina elongate and slender, narrowing dcH-idedly to sharply nninded ai)ex,
