386 REVISION OF THE AMYCTERIDES, ii., 



base almost truncate, humeral angles not produced; disc strongly 

 convex and declivous posteriorly, longitudinally striate, striae 

 narrow, not foveate; interstices slightly raised, each composed of 

 a row of low granules, closely placed in single series, granules 

 equal in elevation, but on lateral interstices becoming transverse 

 and in double series, the whole sculpture somewhat confused. 

 Sides granulate in double series. Undersurface convex; first and 

 second ventral segments transversely strigose, intermediates large, 

 sparingly setigero-punctate; fifth not excavate, a feeble transverse 

 impression present at apex. Dimensions : Q,2Q x 10 mm. 



Hah. — West Australia : York (C. French). 



An aberrant and remarkable species, which it seems hardly 

 possible to refer to Talaurinus. I have seen a male in a collec- 

 tion belonging to one of the European museums, and, except for 

 being more parallel-sided, it did not differ much from the female. 

 I have since seen a pair belonging to the South Australian 

 Museum, which came from Blackburn's Collection. 



Ophthalamycterus, n.g. 

 Type, T. laticeps Macleay. 



Head very broad, strongly granulate. Rostrum extremely 

 short, no longer than head, little excavate; widely ampliate on 

 sides, the width across external ridges less than width of rostrum. 

 Scrobes short, posterior end definite, with a groove leading from 

 inferior aspect towards eye. Eyes small, rounded, very pro- 

 minent, situated distant to ends of scrobes. The rest as in 

 Talaurinus. 



I propose this new genus for a most curious species. In ap- 

 pearance, it seems a typical Talaurinus, but the structure of the 

 head and rostrum, and particularly the curious form of the eyes, 

 seem to warrant its separation from that genus. The eyes are 

 small, but extraordinarily prominent, and present the appearance 

 of the eyes in cases of exophthalmic goitre.
