ACCOUNT OF THE PHASMIDAE, WITH NOTES ON THE EGGS. 



If I am right in considering the two dark specimens as the same species, it is 

 possible that this insect is dimorphic in colour ; there are at any rate no intermediates 

 in our small series. 



(2) Myronides binodis, n. sp. PI. VII, Fig. 2. 



£. Perangustus, testacens, antennis ad apicem pallidioribus ; capite anterius mutico, 

 vertice obsolete quadrituberculato ; metanoto posterius utrinque gibboso. 



Operculo subgenitali convexo, medio prominulo, apice late emarginato. 



Although at first sight similar to M. filum this species is very easily distinguished 

 by the absence of processes on the front of the head, by the binodose metathorax, 

 by the different proportions of the metanotum and median segment, and the prominent 

 male operculum. The curious short sacs attached to the metathoracic gibbosities 

 clearly represent the wings, though they have the texture of the integument in 

 general. 



Long. corp. 76 mm.; antenn. 53 mm.; cap. post antenn. 3 mm.; pronoti vix 3 mm.; 

 mesonoti 19 mm. ; metanoti 8 mm. ; segm. med. 4i\ mm. ; abdominis 38 mm. ; fem. 

 ant. 23 mm. 



Loc. New Britain.

 (3) Myronides bituber, n. sp. 



$. Corpore granuloso, fusco-testaceo, pedibus testaceis fusco-variegatis, antennarum 

 apice albido ; capite processubus duobus acuminatis, magnis armato ; abdomine carinato, 

 carina anterius obsoletescente, segmento sexto medio bituberoso. 



Long. corp. 120 mm.; antenn. 60 mm.; capitis (pone antenn. acetab.) 5 mm.; 

 pronoti 5 mm.; mesonoti 26 mm.; metanoti 9£ mm.; segm. med. 5^ mm.; abdom. 59 mm. 



Loc. New Britain. One specimen. 



Although at first similar to the other species here described this may be readily 

 distinguished by the pair of peculiar tuberosities on the dorsum of the sixth abdominal 



segment. 



Egg (PI. IX, Fig. 33) : 3 mm. long ; capsule covered with numerous large 

 pores, and with a scanty coarse but slightly elevated reticulation ; micropylar area 

 not extending to the operculum, and moderately distant from the opposite pole, rather 

 narrow ; micropylar scar very obscure. Operculum bearing a black sessile capitulum, 

 and surrounding this a slightly elevated ring. Described from eggs deposited by 

 the female in New Britain while in Dr Willey's possession. 



(4) Myronides simplex, n. sp. 



$ . Augustus, cylindricus testaceo-griseus, antennis pedibusque subvariegatis, illis ad 

 apicem albidis, apice ipso minute fusco, articulo primo ovale ; capite superne pro- 

 cessubus duobus distantibus, mediocriter elevatis, acuminatis ; tarsorum anticorum 

 articulo primo snperne alte carinato; abdomine segmento sexto dorsali in medio
