Two additional male specimens have been examined, one a topo- 

 type, the other from Khow Sai Dow, Trong, 1,000 feet elevation, taken 

 in 1899. 



Myronides porus (Westwood)? 



1859. Lonchodes Porus Westwood, Cat. Orth. Ins. Brit. Mus., I, p. 42, 

 PI. VII, fig. 9. [East Indies.] 



One female; Khow Sai Dow, Trong. Lower Siam, 1,000 feet. Janu- 

 ary-February, 1899. (Dr. W. I.. Abbott.) [U. S. N. M.] 



While the female of this species has never been described, the present 

 specimen is in such condition that the more important characters 

 cannot be critically examined. For this reason some uncertainty 

 exists as to the correctness of the determination. 



Genus PHRAORTES Stal. 

 1875. Phraortes Stal, Recensio Orthopterorum, III, pp. 8 and 64. 



Type. — Phasma elongata Thunberg. 

 Phraortes mikado n. sp. 



Type. — ? ; Yokohama, Japan. (Loomis.) [A. N. Caudell.] 



Allied to P. elongatus (Thunberg) {= Phasma ■niponense De Haan), 

 but differing in the character of the lamellar expansions on the median 

 and posterior femora, the carination of the anterior femora, and the 

 non-gibbous sixth abdominal segment. 



Form slender, elongate. Head moderately long, considerably wider 

 anteriorl}'- than posteriorly; eyes circular, moderately prominent; occi- 

 put bearing a pair of acute conical spines, equal in height to the depth 

 of the eye. Pronotum rectangular, longer than Inroad, surface with 

 slightly marked longitudinal and transverse depressions. JMeso- 

 notum over foiu* times the length of the pronotum, suliequal except 

 posteriorly, median longitudinal depression well marked. Metanotum 

 (with median segment) about four-fifths the length of the mesonotum, 

 suljequal except for the gradually expanded ]Dosterior portion, median 

 segment about one-fourth the length of the metanotum alone. Abdo- 

 men considerably exceeding the head and thoracic segments in length, 

 the greatest width l^eing at the third and fourth segments; ninth dor- 

 sal segment tectate, carinate, lateral margins sinuate, the apex with a 

 median triangular emargination which exposes the truncate extremity 

 of the tectate and carinate supra-anal plate; subgenital plate scoop- 

 shaped, compressed, carinate. Limbs \-ery slender, the anterior pair 

 exceeding the others in length. Anterior femora exceeding, by more 

 than the length of the median segment, the combined length of the 

 head, pronotum and mesonotum, subtrigonal in section, superior ex-
