134 NOTES ON AUSTRALIAN COLEOPTERA, 



Five specimens are before me; two, taken by Mr. Cox from 

 Wecldin Forest, near Young, are, I consider, males, as also one 

 taken by Mr. P. Shaw at Canbelego; while two from Forbes, sent 

 by Mr. Alfred Stephen, are both female. If T am correct in this, 

 the male has a remarkable sexual distinction in the abnormal 

 enlargement of the basal joint of the anterior tarsi, which is not 

 found in the female. The same joints of the intermediate tarsi 

 are enlarged to a much less degree in the same specimens. The 

 Forbes (9) specimens are wider and less parallel in form, with a 

 slightly steeper apical declivity. I do not think it likely that 

 there are two species in the above, the only differences (noted 

 above) being entirely referable to sexual characters. 



A. Stepheni is, by its more convex form and more rounded front 

 angles of prothorax, intermediate between Agasthenes and Hypo- 

 cilibe; but I am sure that no student of the Tenebrionidae could 

 place it in a different genus from A. Westwoodi Bates, although 

 one modification of Bates' generic diagnosis is necessary for its 

 reception, i e., the very acute front angles in A. Westwoodi should 

 be considered as a specific rather than a generic character. Types 

 in author's coll. 



Yar. i. a 9 specimen from Mildura, Yictoria, is of shorter and 

 more convex form, buc is otherwise identical with the above. 



Agasthenes Westwoodi Bates. 



I have received an undoubted specimen of this rare insect from 

 Mr. H. Giles of the Zoological Gardens, Perth, taken at Keller- 

 berrin. West Australia. As the unique type, in the British 

 Museum, is without palpi, tarsi, and the five apical joints of the 

 antennae, I will describe these. Palpi and antennae chestnut-red> 

 the maxillary palpi long, with apical joint narrowly cultriform. 

 Antennae with first joint short, thick and cylindrical; second very 

 short and bead-like, joints 3-7 subconic, third about as long as 

 the fourth and fifth combined, joints 8-11 much shorter than the 

 preceding, slightly thickened, more hairy and of a paler red 

 colour, apical joint prolate-spheroidal. Tarsi: anterior and inter- 

 mediate, with basal joint as long as, but not wider than, the
