of females* for the purpose of measuring the index of cranial 

 breadth, amongst which I found many dozens of the well-marked 

 above-mentioned transversal depressions. Many elderly females 

 had the greater part of the depression quite strongly marked, 

 and I found that in some cases the depression was not less than 

 from 3 to 4 millemetres. I possess a skull from one of these villages 

 of the south coast of New Guinea, on which the above-described 

 saddle-ridge is well marked, and I believe this acquired cranial 

 deformation has a great chance of being more or less trans- 

 mitted from generation to generation by inheritance, and is 

 therefore still more worthy of record. A more complete account 

 of these cases of cranial deformation, with measurements and 

 illustrations, will be found in my letter to Professor R. Virchow, 

 of Berlin. [ Vide Sitgungsberichte der Berliner Q-esellschaft fiir

Descriptions of Australian Micro-Lepidoptera. 



By E. Meyrick, B.A. 



VI. TORTRICINA. (Continued) 



The present instalment concludes the Tortricina, so far as they 

 are at present known. It treats of the two remaining families, 

 the Grapholithida and the Conchjlidee, as defined in the preceding 

 paper (No. V.). These families are far less prominent in the 

 Australian region than they are in the Northern hemisphere, and 

 especially in Europe ; their main groups are indeed wholly absent 

 and the representatives of the families consist chiefly of specially 

 developed groups, with scattered outliers of some northern types. 

 Descriptions are here given of 55 species, of which 45 are new 

 to science. 



* Married females in many parts of New Guinea hare the habit of shaving 

 their hair, and present, therefore, for a biologist a more suitable object for 

 cranial measurement than the men with their large frizzled wigs.
