404 Dr. J. L. Hancock's Further Studies of 



Genus Lamellitettix, Hancock. 



1. L. acutus, Hancock, Spolia Zeylanica, ii, pp. 126-128, 



Plate ir, fig. Q-Qh, 1904. 



One male example, No. 9399, from Havahetta, Ceylon, 

 collected by E. Ernest Green ; presented by Malcolm 

 Burr to the University Museum, Oxford. 



This species was described from a female example from 

 Ceylon. The entire length of the male measures 12 mm. 

 from front to end of pronotal process. 



2. Z. i^luriearinatus, sp. nov. 



Body slender, ferrugino-fuscous. Head very little exserted ; vertex 

 subnarrower or equal to one of the rather small eyes, frontal carinula3 

 on each side barely elevated, oblique, subtuberculiform ; frontal 

 costa compressed above between the eyes and the rami protuberant 

 between the antennse ; posterior ocelli conspicuously placed between 

 the lower third of the eyes. Pronotum moderately narrow between 

 the humeral angles, depressed on the process ; dorsum j^luricarinate ; 

 median carina irregularly sinuate, bicompressed forward and poste- 

 riorly depressed but irregularly compressed ; dorsum between the 

 shoulders bearing two supplemental abbreviated carinulae running 

 parallel and compresso-elevated ; prozonal ^carinee and lateral carinse 

 in front of the shoulders distinctly expressed ; posterior process 

 acuminately prolonged reaching beyond the apices of the out 

 stretched hind tibise ; posterior angles of lateral lobes, laminate 

 subacute, angulate, behind little subexcavate but widely and obliquely 

 truncate. Elytral apices rounded ; wings fully explicate nearly 

 reaching to apex of pronotal process. Anterior and middle femora 

 elongate ; third pulvilli of the first posterior tarsal articles nearly 

 as long as the first and second combined and flat below ; the first and 

 second subacute ; posterior tibiae infuscated backward towards the 

 apices. 



Entire length of body, female, 14*6 mm. ; pronotum 13'5 mm.; 

 posterior femora 5*2 mm. 



One example from Deltota, Ceylon, No. 9393, presented 

 by Malcolm Burr to the Universit}^ Museum, Oxford. 



This species is easily recognized by the small vertex, 

 the slender body bearing an extremely acuminate pronotal 

 process, and the laminate, subacute, angulate, lateral lobes, 

 instead of the acute transversely produced angles in 

 acutus.
