the pnu'tit-ally iioii-ui-aniilate elytra will separate it from both P. 

 lemmus and P. (lunumis. In spite of* the granulate head, I reoard 

 it as more nearly related to P. lemmus than to P. (lumosus. Until 

 more field-work is done in collecting these species, T think itcadvis 

 able to maintain the different forms, with the exception of T.pupa, 

 as distinct species. 1 have mucli pleasure in namin*:- this insect 

 al'tei' ]Mr. H. M. Giles, of Perth, from whose collection 1 obtained 

 it. 



Myotrotus Pascoe. 



Pascoe, Jonrn. Linn. Soc. Zool., xii., p. 22. 



Type of genus, Mi/olrolus nhUisus Pasc. 



Head strongly convex. Rostrum short, broad, the upper surface 

 transversely concavo-convex from middle to sides; the external 

 ridges strongly convex in profile, and convex outwardly, strongly 

 incurved to base; internal ridges barely traceable. Scrobes dee]i, 

 wide, arcuate, ending far from eyes. Eyes small, subovate. Sca])c 

 short, strongly incrassate. Prothorax with ocular lo])es strongly 

 produced to touch or i)artly conceal the eyes in certain ]iositions. 

 Elytra with interstices finely granulate. 



A remarkable form, which I prefer to place among the allies of 

 Tfdaurimis rather than among the '"Euomifles,'' an assignment 

 about which Pascoe himself felt doubtful. In the male, the fifth 

 ventral segment is moderately deeply and extensively excavate, 

 somewhat in the fashion of TalaiiriHus apici-hirlns. The curiously 

 shaped and strongly convex, external, rostral ridges, the very sliort, 

 thickened scape, and the strong, ocular lobes afford the most strik- 

 ing characters of the genus.

 To this species. I would refer several si)ecimens in the Macleay 

 ^fuseum. though they show slight variation inter se in the elytral 

 granules. A specimen IQ) I'eceived some years ago from the late 

 j\lr. George Masters, was sent to the British ]\Iuseum for compari- 

 son with the type. In reply, ^Ir. K. G. lilair writes: "Yes. n Mi/n-
