Family BYRRHIDAE 



PART II. 

 Plate xxxii. 



Since the date of the publication of my catalogue of the Australian Byrrhidae (^) 

 only two new species of the family lia\-e been descrilied, namely : 

 Microchactcs br\ot^Iiilus Lea. Proc. Linn. .Soc. N.."^. \\'ales. xxxvi, 1911. p. 462. 

 Chclonariiiin aiistroliniiii Lea. Rec. S. Aust. AIus. i, 1918. p. i<7, pi. i, fig. 3. 



In januarw l'''lt>. Air. IL J. I'arler and I jiaid consideral:>le attention to moss 

 in the western parts of Tasmania, and obtained several new and beautiful species 

 of Pcdilof'lionis. and other moss-frequenting species; these are herein described, 

 together with other members of the famil)'. ( )f the total species now known 

 almost half have only been taken in Tasmania, hut this can be simply because 

 moss has been worked to a greater extent there than on the mainland; when it 

 has been more fullv examined in Xew .South Wales and Queensland, many 

 additional beautiful species of the family will doulitless be recorded. 



The Australian genera, disregarding some of the more certain but less easily 

 seen characters, may be thus distinguished : 

 A. Eyes concealed with head at rest ... ... ... Microchacfes 



\A. Eyes not concealed 



B. Head entirely concealed from above ... ... Clicloiiariiim 



BH. Head not entirely concealed from above 



C. Mandibles concealed with head at rest 



a. Base of prothorax and of elytra 



strongly sinuous ... ... Byrrhiuus 



aa. Base less strongly sinuous ... Liiunicliiis 



CC. Mandibles not concealed with head at rest 



D. Apterous ... ... ... Pedilopliuius 



DD. Winged 



E. Eyes very prominent ... Aspidiplionis 

 EE. Eyes but little prominent Morychiis
