The distal borders of the wings, upper surface, in thoosa 9 

 are not buff as in var. luna; the whole under surface is more 

 buff and has more prominent markings than ? 2 of poly- 

 phemns, but less than luna. The ocelli are more pronounced 

 than in M. thoosa $ , but much less so, and less numerous than 

 in luna or polyphemus. Apex of forewings heavily marked 

 with black as in $ $ , and general color of a greener pearly- 

 lustre than in the two other forms. To describe further were 

 to repeat my former description of the $ . The accompanying 

 illustration best contrasts the two sexes of M. thoosa with 

 those of M. polyphemus; the upper pair are M. thoosa; the 

 lower, M. polyphemus as typical as I could select from 126 

 specimens. The figures are reduced one-half. 



As far as I can learn, M. thoosa belongs to the eastern coast, 

 and M. polyphemus and luna to the central and western portion 

 of Mexico. 



A new Species of Phoebolampta (Tettigonidae, 

 Orthoptera) from Cuba. 



By JAMES A. G. REHN. 



Phoebolampta cubensis n. sp. 



Type:? ; Havana, Cuba. (C. F. Baker.) [A. N. S. 



Phila.] 



Closely allied to P. magnified Brunner* from Haiti, but very 

 considerably smaller and with the costal margin of the tegmen 

 much more sinuate in the distal half, and apparently with a 

 greater number of spines on the distal section of the ventral 

 margins of the caudal femur. 



Size medium ; form distinctly compressed. Head gently sloping to 

 the produced, subequal fastigium, which is very slightly elevated, 

 with a very fine slight median sulcus and a subtruncate apex ; facial 

 fastigium touching the fastigium of the vertex ; eyes moderately large, 

 subspherical, quite prominent when viewed dorsad; antennas filiform, 

 in length distinctly exceeding the body and about equal to two- 

 thirds the length of the tegmina. Pronotum with the dorsum flattened 

 and regularly expanding caudad, the cephalic width about one-third 

 the caudal, cephalic margin truncate, caudal margin arcuate with the 

 faintest possible indication of angulation, lateral angles rcctangulate 

 but not sharp ; disk punctate, much more thickly so caudad than
