Male greenish-yellow, the tegmina and wings darker; female fuscous- 

 brown, the head, pronotum, sides of metanotum and femora and terminal 

 abdominal segments more or less blotched with chalky white; males with 

 sides of tegmina and abdominal segments usually marked lengthwise with 

 white. Pronotum subquadrate, deeply impressed transversely, the front 

 portion with a faint longitudinal impression and a pair of short black-tip- 

 ped spines, hind one with a pair of similar but smaller spines in female- 

 mesonotum of male with eight or ten, of female with 20 or more, scattered 

 similar spines. Tegmina very short, oval, strongly veined, their tips 

 obliquely rounded; wings oblong, projecting 2 or 3 mm. beyond the teg- 

 mina. Front legs more slender, and but slightly longer than middle ones 

 their femora with basal third strongly narrowed and more or less curved; 

 middle and hind femora of female with their dorsal carinse crested near 

 apex. Apex of male abdomen moderately enlarged, the seventh and 

 eighth segments subequal; ninth slightly shorter, subquadrate; the sev-

 drical, blunt, decurved, a little shorter than the ninth segment. Length

This is the only winged Phasmid known from the United 

 States. The first specimens were taken at Loggerhead Key, Dry 

 Tortugas, Fla., and were recorded, described and figured by Cau- 

 dell (1904) as Haplopus cvadue Westwood, a Santo Domingo spe- 

 cies. A number of additional specimens, taken later on the same 

 island by Dr. A. G. Mayer, were afterward submitted to the same 

 authority, who concluded that his first identification was wrong, 

 and described them (loc. cit.) under the name they now bear. In 

 1912, R. & H. visited Loggerhead Key and secured a number of 

 specimens, finding them only on bushes of the bay cedar, Suriana 

 IIKI rit i HKI L. They record (1914c, 387) the .species also from Bird 

 Key and Garden Keys of the Tortugas groups, and from Key West 

 and Long Key, July 3 13. It is also known from Key Largo and 

 Everglade, Fla., a specimen from the latter point, taken by Davis, 

 being the only one known from the mainland of the State. The 

 large size and bizarre appearance of this Phasmid suggest its trop- 

 ical origin, and it is very probable that in time it will be found 

 to inhabit some of the adjacent West India Islands, while in Flor- 

 ida it will probably be found only in the subtropical area of the 

 extreme southern portion. 



Subfamily III. ANISOMORPHINJE. 



Rather short, robust species having the antenna 1 more than 

 twice as long as front femora ; mesonotum not more than three
