82 NOTES ON SOME REMARKABLE TASMANIAN INVERTEBRATES. 



tarsi, 15 [10] ; tegmina, 19 [2^]; wings, 20 [3] ; total length 

 (iiK'ludiug anal styles), 17Ut [102]. 



Habitat, Burnie. 



(Presented to the Tasmanian Museum by Miss Dora 

 Sboobridge.) 



The specimen (a female) appears to be somewhat dis- 

 coloured, as tbere are traces of green on the mesotborax 

 under surface of teginina and anal styles ; the ovipositor is 

 also somewbat damaged. The large tooth of tbe intermediate 

 tibiae is single on the left, but; doubie on tbe right. 



Tbe species appears to be allied to A. chronus (West- 

 wood, Catalogue of Phasmidse, p. 114, supplementary plate Y., 

 fig. 2), but should be distinct on account of the posteriorly 

 inflated fourth abdominal segment and large teeth of tbe 

 intermediate tibiae. From Westwood's figure it differs in the 

 shape of the tegmina and length of wings ; the latter, how- 

 ever, are described as being very variable in length. The 

 colours of tbe wings are very different to those given for 

 chronus, the membranous portion being entirely black, whilst 

 in the figure it is drawn (and also so described) as being 

 variegated. The serrations and spines of the legs are also 

 very different to those on Westwood's figure. 



An immature specimen, evidently belonging to this species, 

 was presented to tbe Department of Agriculture by Mr. 

 W. C. Weymouth. Irs antennae consist of but 24 joints each. 

 The spines and serrations of the legs are the same as in the 

 type, even to the peculiar dentition of the intermediate 

 tibiae. Tbe tegmina '^nd wings are very small, of almost 

 equal size and shape, and of a dull greenish yellow, with 

 thickened edges, they look like scales. The general colour of 

 tbe body is rather paler than that of the type. 



* The lengths given in brackets are those of the immature specimen, 

 t It is, therefore, the longest (although not the largest) insect at present known, 

 to occur in Tasmania.
