which is rounded and entire, exposing the two broad setose 

 anal styles ; the upper surface is varied with slender lon- 

 gitudinal raised lines. The operculum does not extend 

 beyond the extremity of the eighth dorsal segment. The 

 fore legs have the femora rather thickened, with five or six 

 serratures on the inner edge ; the four hind legs are rather 

 slender, with two or three minute spines on the under side 

 near the tip. 



A somewhat larger specimen than the one represented in 

 Plate VIII. fig. 10, has the fore femora armed with only 

 three serratures, and the hind femora have three small 

 equidistant spines between the base and middle of the 

 upper edges.

Long and slender ; the male very slender and filiform, 

 entirely of an obscure red-brown colour, with the surface of 

 the body smooth, except the upper surface of the meso- 

 thorax and base of the metathorax, which are densely 

 covered with very minute granules. The head is of mode- 

 rate size and unarmed. The metanotum of the male is 

 simple ; but that of the female is furnished with two 

 minute, free, moveable, oval, reticulated scales, resembling 

 rudimental tegmina. The abdomen is long and simple ; 

 *he terminal segments in the male are short, forming an 

 oval mass, the last terminated by two small lobes exposing 

 the short caudal styles. The terminal segments of the 

 female exhibit a structure I have rarelv met with in the 



family : the ninth segment has its apical outer angles 

 rounded, with the short anal styles visible at the sides ; 

 the extremity is slightly emarginate, exposing a minute ter- 

 minal rounded lobe. The operculum is long and deeply- 

 incised at the tip ; it extends far beyond the terminal seg- 

 ment, and is accompanied on either side by a slender com- 

 pressed elongated style, channelled externally, with a deep 

 slit at its apical end, and with the extremity of its upper 

 edge prolonged into a spine, detached and lying outside of 

 the upper edge of the lower division ; within the space thus 

 formed lie two long and flattened slender filaments, nearly 

 as long as the operculum, incurved towards their tips. The 

 legs are long, slender, aud simple ; all the tarsi, however, 

 have a small node at the base of the first joint, which is 

 setose on the under side.

The appendages of the operculum of the female are 

 similar to those in Ph. Zeuxis, as well as in Ph. galac- 

 pterum, Maclclottii, and Hadrillus. 



Genus 14. PHIBALOSOMA. 



Phibalosoma (male), Cladoxerus (male), and Cladomorphus 



(female), G. R. Gray, Serville. 

 Cladoxerus, Burmeister, Serville. 



.Males with wing-covers and wings. Females apterous. 

 Head destitute of ocelli. Legs long, and generally spined. 



Males very long, slender, and cylindrical. Mesothorax 

 several times longer than the prothorax. Metathorax 

 shorter thau the mesothorax. Tegmina small, much shorter 

 than the metathorax, oval. Wings small, or of moderate 

 size. 



Females more robust, with much shorter legs. Ovi- 

 duct generally extending beyond the extremity of the 

 abdomeu. 



Considering the possession of a pair of wings in the 

 males and the absence of alary organs in the females as the 

 leading character of this group, we find several distinct 

 types of structure among the males as well as amongst the 

 much fewer females with which we are acquainted. The 

 males of Phibalosoma serratipes and Rypharpax, for in- 

 stance, have the terminal dorsal segment of the body
