456 MR. W. F. KIRBT ON NEW OR RARE 



metanotiim ; the latter, however, are deserihed hy Stal as squamiforni rudiments of 

 wings. The tibiae and tarsi are described as compressed and dilated ; but in the male 

 before me they are hardly to be called compressed, and there is only the faintest indication 

 of a dilatation at the extremity of the front tibiae. As this character is usually much 

 more strongly marked in the females than in the males, the female of Stal's insect would 

 probably more resemble those of the genus Dixippus ; and having both sexes of 

 C. TFoodfordi before me I have thought it more satisfactory to treat it as the type of a 

 new genus. 



Gbeenia, gen. nov. 



Cylindrical ; head with two acute spines between the eyes, rising from a ridge ; body 

 granulated ; legs moderately long and slender, unarmed, except for a small rounded 

 lobe on the upper surface towards the base of the middle femora in the female, terminal 

 segment carinated (at least in female) and ending in a wide obtuse fork. 



This cui'ious genus is not closely allied to any other. Bates described and figured 

 both sexes of a Phasmide under the name oi Lonchodes furcatus in Trans. Linn. Soc. xxv, 

 p. .335, pi. xliv. figs. 5, 6, from Ceylon. Among some PhasmidcB recently brought from 

 Ceylon by Mr. E. Ernest Green, to whom the British Museum has been indebted for 

 so many interesting additions to its entomological collections, I find a female of this 

 species, and have much pleasure in calling the uncharacterized genus to which it belongs 

 after Mr. Green, who is, I may mention, at present engaged on a monograph of the 

 Coccid(JS of Ceylon, a large and practically; unworkcd subject, of great importance to 

 planters and agriculturists. Mr. Green's insect agrees in all essential points with 

 Bates's figure, except that it is apparently less strongly granulated. In the absence of 

 a series, it would be foolish to describe the insect as new, on this doubtful character 

 only.

Hermogenes, Stal, Rev. Ortli. iii. p. 8, note (1875). 



Prisomera, pt., Gray, Syu. Phasm. p. 15 (1855); Westw. Cat. Phasm. p. 47 (1859); Brimn. Ann. 

 Mus. Genov. xxxlii. p. 81 (1893). 



Under the present genus we may include : — 



1. Lonchodes per sonatus, Bates, Trans. Linn. Soc. xxv. p. 33G, pi. xliv. fig. 7 (1865), from Bouru. 



2. Phasina femorata, Stoll, Pliasm. p. 44, pi. xiv. fi^. 54 (Amboina). 



3. Phasnia (Acanihoderus) verrucosum, De Haan, Orth. p. 136, pi. xiv. fig. 1 (Sunnatra). 



(The type of Prisomera, Gray, is his spinicolUs from Ceylon, Avhich is not congeneric 

 with these.) 



Female. Body cylindrical, granulated, not spiny, but sometimes with lobate excres- 

 cences on the back ; antennae slender, generally shorter than the front legs ; legs 

 short, femora spiny beneath, legs more or less compressed, especially the front tibiae ; 

 all the femora dentated beneath at the extremity ; front and intermediate femora 

 and tibife more or less foliaceous ; first joint of front tarsi not much longer than 

 the second.
