544 Mr. C. O. Waterhouse's Notes on 



infuscated on the disk. There are two specimens in the 

 British Museum of an insect which I have little doubt 

 belong to S. Jansoni; they differ only in not having the 

 sides of the thorax yellow. ^S*. lobicollis is extremely 

 close to S. Jansoni, and I think wall probably prove to be 

 only a variety of it ; it differs in not having the green on the 

 apex of the elytra and in having a series of large punc- 

 tures on the fifth interstice of the elytra. 



The following insect appears to be sufficiently distinct 

 from *S'. limbata to merit description, although I cannot 

 give it specific rank: — 



Stigmodera limbata, var. ? 



Viridi-nenea, thoracis lateribus elytrisque rufis ; thoracis 

 marginibus incrassatis ; elytris striatis, interstitiis con- 

 vexioribus. 



Long. 9|— 131 lin. 



Differs from the ordinary form of *S'. limbata in having 

 the margins to the thorax more decidedly thickened, with 

 a tendency to be angular in the middle. The elytra are 

 deep red, with the margins rather paler ; there is scarcely 

 any trace of aeneous on the suture, and the interstices are 

 more convex than is usual in the ordinary form of S. 

 limbata. 



Hab. — Queensland and S. Australia. Coll. Brit. Mus. 



In the Museum collection there is an insect which I 

 believe to be the female of S. sanguineocincta, the type of 

 which is a male. The type specimen has the thorax 

 uniform bright green, with a smooth sutural line slightly 

 raised, and with a transverse smooth line near the front 

 margin. The $ has this same peculiarity, but has the 

 sides somewhat incrassated. The elytra are uniform 

 brownish-yellow (without any red margin), and the apex 

 of each elytron is very slightly emarginate ; the interstices 

 of the stria3 are distinctly but not thickly punctured, 

 whereas they are almost destitute of punctures in the male. 



Note. — The sculpture of the thorax and elytra in many 

 of the species of Stigmodera appears to be of a coarser 

 kind in the females than in the males. This is particu- 

 larly noticeable in S. Mitchellii. Besides the differences 

 of sculpture, the sexes of some species of this genus differ 

 in coloration, e. g., S. Klugii has two yellow bands on the 

 elytra in the male, the female having an additional yellow 

 spot on the shoulder. The sexes of S. Duboulayi differ
