DICTYOPHORUS Thunb. 



Stal has restored this generic name of Thunberg with E. microptera as 

 the type. In this he is undoubtedly correct, and should be followed. Bnt 

 when he separates from it those species which have the vertex slightly 

 deflexed, and places them in a new genus, Taniopoda, his desire to form 

 new genera would seem to overcome his better judgment and accurate 

 knowledge of this group. Although it is true that the vertex is somewhat 

 sloped, yet it is but slightly so, and scarcely varies from the line of the 

 anterior part erf the pronotum and occiput. An examination of his T. pic- 

 ticornis, a specimen of which is now before me, shows that it is congeneric 

 with R. iitiernptcra, and if removed from association with that genus it must 

 be arbitrarily done. Therefore, while I cheerfully follow Stal in separating 

 the miles form from the microptera form, I cannot accept his new genus 



T(cniopoda. 



DICTYOPHORUS PICTICORNIS, Stal. 



Rhomalea pecticornis, WALK., Cat. Dermap. Salt., iii, 538. 

 Tccniopodapicticornis, STAL, Recensio, 51. 



Walker's specific name would take precedence but for the fact that it is 

 certainly incorrectly printed. For the benefit of American entomologists I 

 give here a somewhat complete description from the specimens before me, as 

 Walker's description is somewhat deficient (as given in my Synopsis), and 

 Still's not generally accessible. 



Female. Robust ; similar in form and size to It. centurio (microptera ) 

 Head depressed ; the top from the middle of the occiput to the tip of 

 the vertex sloped slightly downward in a line with the top of the 

 anterior lobe of the pronotum ; seen from the side, it forms with the frontal 

 costa an angle of about 110. Vertex slightly produced in front of the 

 eyes ; the sides meeting in a right angle ; sin-face flat ; margins slightly 

 elevated. Frontal costa narrow, slightly expanded at the ocellus, obliterated 

 before reaching the clypeus, sharply sulcate. Antennse somewhat elongate, 

 extending slightly beyond the tip of the pronotum, acuminate ; joints dis- 

 tinct. Pronotum slightly expanding posteriorly ; the dorsal portion elevated, 

 being arched from the lateral carinse so that the portion above these equals 

 in height two-thirds the portion below them ; the crest forming an obtuse,
