ACCOUNT OF THE PHASMIDAE, WITH NOTES ON THE EGGS. 



This egg is remarkable on account of the absence of sculpture on the capsule ; 

 the stalk of the capitulum forms a conical process the terminal part of which projects 

 into the pallid membranaceous top of the capitulum. 



It is possible that Stoll's 1 figure of the male 2 and female 3 of "Le spectre a ailes 

 tachetees" may have been taken from this species. The locality he gives was, however, 

 "Amboina," and the form of the cerci does not agree. His figure has been universally 

 applied by synonymists to the following species, viz. A. confusu.

Cyphocrania metadata. Westwood, Cat. Orthopt. Phasmidae, p. Ill [nec Serville]. 



Fern. Elongata ; mesothorace obsolete parceque granoso ; cercis latis, alis fusco- 

 brunneis, hyalino-maculatis. 



Antennis brevibus, parce pubescentibus, ocellis subobsoletis ; cercis brevibus, ro- 

 tundatis ; operculo minus obtuso, paulo ultra abdominis apicem extenso, medio carinato ; 

 processubus genitalibus inferioribus elongatis apicem laminae sub-analis attingentibus ; 

 processubus medianis inferioribus fere aequalibus ; proc. superioribus elongatis, gracilibus. 



Long. corp. 156 mm.; pronoti 7| mm.; mesonoti 27 mm.; metanoti 8 mm.; segm. 

 med. 9 mm. ; abdom. 94 mm. ; cerci 4 mm. ; lat. 2£ mm. ; tegm. 27 mm. ; alae 62 mm. 



Loc. New Britain. 



This species was met with by Dr Willey in two examples of the female sex, 

 and an extremely decayed male. It is readily distinguished from A. stolli by the 

 almost smooth thorax, and the more elongate, middle and superior (lateral) genital 

 filaments ; as well as by the rounded apices of the cerci. The male has three large, 

 instead of six small, teeth on the inflexed margin of the last dorsal plate of 

 the body (PI. IX, Fig. 18). 



This species is the Cyphocrania maculata of Westwood, according to specimens in 

 the British Museum. Westwood was, however, in error in considering this to be the 

 species designated by Stoll, Serville and others as C. maculata. Stoll did not at first 

 give his species any name, but Serville and others took his figure as the type of their 

 species, and if their assignment of a name on such grounds be attended to at all 

 we must give a new name to Westwood's Insect. The name Phasma necydaloides, 

 subsequently assigned by Stoll to his species, was then pre-occupied by Linnaeus. 



The figure of Platycrana necyelaloides in the Voyage au Pole sud may possibly 

 have been taken from a specimen of this or an allied species. It exhibits the thorax 

 as entirely smooth. It is from the island of Warou. 



Egg (PL IX, Fig. 29): 4£ mm. long, 3^ broad; slaty-black, densely covered with 

 rugose sculpture. Micropylar area, narrow and compressed so as to be strongly raised, 

 and to form a sort of band extending from the operculum to near the other pole 

 of the egg : the micropylar scar coarse but not very distinct on account of the coarse, 

 uneven, neighbouring sculpture, almost V-shaped. Capitulum small, pallid, placed on 

 a short black stalk, obconic so as to be with the stalk almost funnel-shaped.
