remaining seven with some confidence, and the other two witli 

 more doubt. I shall refer to them more particularly in the 

 following pages. One of them, however ( Rottj, 1 have already 

 discussed above. 



After Burmeister there was a long interval, until in 1871 

 Macleay described a single species (11. plnguis). There are 

 two specimens (one of them doubtless the type) bearing this 

 name in the Australian Museum, and they are identical with 

 the Tlaplonycha that I have discussed above as "obesa, Burm. 

 (? Boisd.)". I may here remark that obesa, Boisd., is repre- 

 sented in the South Australian Museum by the species that I 

 am convinced is pectoralis, Blanch. 



In 1878 Mr. Tepper described a species of this genus 

 under the name destructor (Tr.R.S.S.A.), which I have 

 already discussed (Pr.L.S.N.S.W., 1890, p. 533). 



In 1888 (Pr.L.S.N.S.W., p. 913) Sir W. Macleay describ- 

 ed //. testaceipennis. 



In 1890 I described a number of new species (I.e.) in a 

 paper that I have already referred to in the present memoir, 

 and I added other species in 1892 and 1895, all of which are 

 treated in the following pages. 



In 1891 E. nitidicoUis was described (D.E.Z., p. 263) by 

 Nonfried. As the description is so vague as not to mention 

 even the number of joints in the antennae, or, indeed, any 

 other character that would enable me to place the insect in 

 my tabulation, I am oblie^ed to disregard it altogether. 



I have now referred to all the names (to the best of my 

 belief) that have been up to the present time proposed for 

 species that are, in my opinion, or have been treated by their 

 authors as members of tnis genus (including Golpochila ). O^ 

 those (43 in number) I have indicated 7 as representing 

 species that cannot remain in Tlaplonycha, 3 as synonyms, and 

 2 concerning which I have not sufficient data for forming any 

 decided opinion. There consequently remain 31 names which 

 I regard as representing valid species of Baplonycha. I have 

 now to add the descriptions of 29 new species, bringing the 

 total of this genus to the formidable number 60, the dis- 

 tinctive- characters of which are displayed in the following 

 tabulations : — 



Group I. 

 [Antennae consisting of only eight joints.] 



A. Pronotnm not having a fringe of long 

 pilosity immediately within the basal 

 and apical n^argins. 

 B. Head very finely and closely (con- 

 flnently) pnnctnlate. Sides of pro- 

 thorax not sinuate behind middle... rnfioeps, Burm.
