Scitala jmlUdula, Macl. I have examined the type spe- 

 cimen in the Macleay Museum. Unfortunately there is no 

 means of determining its sex. It seems to be a typical Scitala 

 (the unusual shape of the clypeus being disregarded) if it be 

 a female; but if it is a male the short laminae (three in num- 

 ber) of the antennal flabellum, together with the peculiar 

 clypeus may justify Macleay's suggestion that it "should per- 

 haps form a new genus." Its place in my tabulation ( infra) 

 indicates its principal characters. The exceptional shape of 

 its clypeus makes it stand in Byrrhomor'pha in my tabulation 

 of Serlcoid genera (Tr.R.S.S.A., 1898, pp. 32, etc.). Vide, 

 infra, under heading Byrrhomorplia. 



Sericesthis parvipes, IBlsickh. -- Anodontonyx. 

 Sericesthis planiceps, Blackh. — Anodontonyx. 

 Sericesthis pruinosa, Dalm. The type of Sericesthis, as 

 distinguished from Scitala. 



Sericesthis pruinosa, Blanch. Nam prccocc. = Scitala 

 rugosula, Har. 



Scitala pruinosella, 3renske = Se7'icesthis. 

 Sericesthis pidlata, Boisd. Described in seven words. 

 Quite unrecognizable. "Elytris sub torn enfo sis" seems incon- 

 siste^nt with its being a true Scitala. 



Scitala rugostda, Ha,T. = Aiiodontonyx. 



Scitcda suturalis, Macl. — Sericesthis^ as distinct from 

 Scitala. I have examined the type. 



Sericesthis cervina, Boisd. In the Macleay Museum is 

 a specimen bearing a label on which Mr. W. S. Macleay wrote 

 ''Sericesthis cervina, Dej. N.S.W." As it is probable that 

 the specimen is a co-type, and as it agrees with Boisduval's 

 pseudo-description, there can be little doubt that it is 

 the genuine thing. In former memoirs I have expressed the 

 opinion that S. cenmia, Boisd. could not be determined with- 

 out inspection of the type. As the specimen in the Macleay 

 Museum is a B eteronyx I need not discuss it further here, but 

 shall hope to do so in the next of this series of papers. 



To the nine species which I regard as at present consti- 

 tuting the genus Scitala I have now to add ten new species. 

 The following is a tabular statement of the characters by 

 which the species of Scitala can be distinguished inter se. 



A. Antennae consisting of only 8 joints. 

 B. Hind angles of pronoium conspicu- 

 ously explanate and upturned ... riigosiceps. Blanch .(? ) 

 BB. Hind angles of pronotum not as 

 "B." 

 C, Forehead non-rngulose and not 

 nearly confluently punctured. 

 D. Pronotum extremely convex 

 longitudinally (i.e., viewed 

 from the side) ... ... ... convexicollis, Blacl-b.
