CONOCEPHALUS LONGICORNIS Redtenbacher 



Conocephalus longicornis Redtenbacher, Verb, zool.-bot. Ges. Wien, vol. 41, 

 1891, pp. 496, 513. 



One female from Pelaboean Ratoe without date. 



CONOCEPHALUS, species 



One female nymph from Buitenzorg in March apparently belongs 

 to neither of the above species. 



Subfamily Listroscelinae 



XIPHIDIOPSIS FALLAX Redtenbacher 



Xiphidiopsis fallax Redtenbacher, Verh. zool.-bot. Ges. Wien, vol. 41, 1891, 

 pp. 531, 532. 



One male, Mount Salak, May 15. The pronotal disk of this speci- 

 men has a mesial longitudinal yellowish stripe. 



HEXACENTRUS MUNDA, var. SIMILIS, new variety 



This differs principally from typical munda from the Moluccas in 

 having the antennae with the widely separated black bands present 

 only in the apical half of their length instead of their entire length, 

 and by having the posterior margin of the pronotal disk distinctly 

 emarginate, a condition scarcely indicated in the typical form. The 

 glassy oval of the auditory organ of the tegmina is also slightly less 

 elongate in the Javan form. Size as in munda. Described from one 

 male from Buitenzorg, Java, in March. 



Type in National Museum. 



Type.— C&t. No. 27906, U.S.N.M. 



HEXACENTRUS UNICOLOR Serville 



Hexacentrus unicolor Serville, Ann. Sci. Nat., vol. 22, 1831, p. 146. 



One male and one female, Mount Salak, without date; one male, 

 Buitenzorg in March; one female, Depok, August 1. Also two female 

 nymphs probably belonging here, a medium sized one from Pelaboean 

 Ratoe without date and a smaller one from Buitenzorg in March. 



Subfamily Eumegalodontinab 



ELLATODON, new genus 



The use of the genus Eumegalodon Brongniart for the species hlan- 

 chardi by Kirby ° is unwarranted, EmegalodonwsiS proposed to replace 

 the preoccupied genus Megalodon of Brulle, and thus its type is ensi- 

 jer, the same as that of the replaced genus. Being later than Walker's 

 genus Lesina the genus Eumegalodon falls into synonmy under that 

 genus. 



The type of Lesina Walker is the species lutescens of that author; 

 the type of this species was casually examined some years ago in
