DICTYOPHORUS Thunb. 



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



the type. In this lie is undoubtedly correct, and should be followed. But 



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



denexed, and places them in a new genus, Tceniopoda, 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 of the pronotum and occiput. An examination of his T. pic- 



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



with B. microptera, 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 



Ticniopoda. 



DICTYOPHORUS PICTICORNIS, Stal. 



Rhomalea pecticomis, Walk., Cat. Dermap. Salt., iii, 538. 

 Tceniopoda pieticornis, 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 

 Stal's not generally accessible. 



Female. — Robust; similar in form and size (to B. 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; surface flat: margins slightly 

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

 before reaching the clypeus, sharply sulcate. Antenna; 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,
