The previously unknown male of this species in general appear- 

 ance resembles much more closely males of Timanthes than those of 

 the other heavier and much less delicate species of Phyllomimus. 



We note the following characters of interest for this sex. Tegmina 

 ample, costal margin very weakly convex and sutural margin almost 

 straight from the broadly convex margin of the anal field to the distal 

 extremity, where these margins curve into the very broad, transverse 

 and scarcely convex distal margin. Wings extending caudad as far 

 as tegmina. General coloration pale green, immaculate except for a 

 few very small brown flecks, each mesad in the larger tegminal areo- 

 lae. Dorsal margins of fermora lamellate and very microscopically 

 serrulate. Ventral femoral margins armed with spines, which are 

 very minute on the cephalic femora and almost as small on the 

 median femora, as follows. Cephalic internal 2 and 3, cephalic ex- 

 ternal 0, median internal 6 and 6, median external 8 and 9, caudal 

 internal 12 and 15, caudal external 13 and 18 (of which about 10 to 

 12 are distinct). 



Phyllozelus abbotti 59 new species. 



Though in many respects resembling Phyllomimus closely, the 

 species of this genus may be quickly separated by the bispinose 

 prosternum, acute tegmina, with branch of median vein sharply 

 bent and thence parallel to the straight ulnar and median veins, 

 limbs with genicular lobes bluntly triangular, caudal femora with 

 ventro-external margin not lamellate but well spined and other 

 less striking features. 



The present insect apparently differs from the previously known 

 species in having the dorsal margin of the caudal femora only 

 minutely tuberculate. 



From P. siccus (Walker) it differs further in the ventral margins 

 of the pronotal lateral lobes, which show a weak, rounded obtuse 

 angulation, while the caudal tibiae have the dorso-internal margin 

 minutely serrulate. Walker's descriptions of signatus and brevi- 

 usculus are too vague for any definite comparison, though they 

 appear to be based on forms agreeing much more closely with siccus. 



From P. genicularis Saussure and Pictet, it differs further in the 

 decidedly smaller size, immaculate anal field of the tegmina, pro- 

 portionately narrower tegmina, ovipositor which is shorter than 

 the caudal femur, in the unarmed ventro-caudal margins of the 

 cephalic femora and in the spines of the ventro-external margins 

 of the caudal femora, which increase evenly in size distad.

 nvaluable collections in the Malayan region.
