XIX. Further Studies of the Tetriginse (Orthoptera) in the 

 Oxford University Museum. By J. L. Hancock, 

 M.D., F.E.S. (Chicago.) 



(Second Paper.) 

 [Read June 3rd, 1908.] 



Plate XXII. 



The author takes this opportunity to acknowledge his 

 gratefulness to Professor E. B. Poulton, F.R.S., Hope 

 Professor of Zoology in Oxford University, for the privi- 

 lege of studying the remainder of the collection of 

 TetriginsR {Orthoptera). The latter collection consisted of 

 one hundred and thirty-eight examples. Of this series, 

 which are representative of widely varied localities, a 

 number are new, some proving to be unique types. Still 

 others are of historical value, having been collected by 

 Wallace in the Malay Archipelago, and by Bates on the 

 Amazon in South America. These insects formed part 

 of the notable collection of W. W. Saunders, which was 

 purchased and donated by Mrs. F. W. Hope to the Hope 

 department of Zoology, University Museum. The author's 

 first paper on the collection of Tetrigin[& in the University 

 Museum appeared in the Transactions of the Entomological 

 Society of London ; * the present paper is a continuation 

 of that contribution. 



Section LOPHOTETTIGI^, nov. 



In this new section the body has a general resemblance 

 to TripetalocersR. The vertex is often greatly widened, 

 transverse, the eyes substylate ; the structure of the 

 antennae is especially characteristic, being filiform and 

 strongly incrassate, or toward the apices often more or 

 less gradually but distinctly flattened or dilated ; the pro- 

 notum is more often truncate anteriorly or little excavate 

 at the middle of the front margin, and backwardly pro- 

 longed into a posterior process ; the median carina between 

 the shoulders frequently compresso-cristate or the dorsum 

 strongly compressed and foliaceous; the lateral lobes of 

 pronotum more or less laminate, reflexed outwards, and
