the marks made on paper by the wetted human finger-tip. 

 In many Aspiclioti the abdominal segment presents a sort of 

 velvety appearance, from very faint and numerous fine stria? 

 which may be detected upon it ; but I do not know any 

 species which exhibits all over the body such conspicuous 

 striations as in A. eucalypti, with the exception perhaps of 

 A. thecB, as noticed presently.

Mr. Tepper informs me that the specific name of this 

 insect was given by Mr. Crawford in honour of Sir A. Boss, 

 Speaker of the House of Assembly, Adelaide, who first col- 

 lected it. I have received specimens from Mr. Olliff on 

 Xantlwrrhcea.

The adult male of this species does not present any remark- 

 able features, except that a fair proportion of the specimens 

 which I have examined this year have been apterous. I have 

 preserved a specimen of the male pupa which shows in a very 

 interesting manner the transformation of the insect. The 

 general form is elongated -oval, with a projection at the 

 posterior extremity simulating the abdominal segment and 

 pygidium of the female ; at the cephalic end a commencement 

 may be detected of the separation of the head from the thorax, 

 and at the sides the rudiments of wings can also be made out ; 

 the eyes are distinctly being formed : but there is not yet any 

 trace of antenna? or feet ; and in the middle the larval rostrum 

 still remains attached. 



These male specimens were sent by Mr. Koebele, on 

 Bauksia sp., Sydney.

I give a figure illustrative of the " lattice- work " pattern 

 visible on the dorsal abdominal surface of this insect ; the 

 smaller spaces making up the whole patch may differ slightly 

 in arrangement in various specimens. 



This insect exhibits conspicuous fine transverse striations 

 of the epidermis, as in A. eucalypti. Also, in many specimens, 

 though not in all which I have seen, there is a deepish groove 

 nearer to the cephalic than to the abdominal extremity : as 

 this is not absolutely constant I did not include it in the 

 specific characters.
