160 REVISION OF THE GENUS PAROPSIS, 



aggregate. These species, however, could not be placed in any 

 of Chapuis' other aggregates, and I proposed to form them into a 

 separate aggregate to stand as No. ii. Among the species sub- 

 sequently brought under my notice, however, are several which 

 so decidedly link to this newly formed aggregate that which I 

 have called the fifth (and which Chapuis called the second) group 

 as to require the characters of the former to be altered in order 

 to admit into it my Group v. (Chapuis' Group ii.). In my 

 former tabulation of the Groups of Paropsis I altered Chapuis' 

 classification otherwise by transposing the position of its Groups 

 iii. and iv. and also regarded its two subdivisions of its Group 

 iv. as primary divisions of the genus. To these alterations I 

 adhere, and therefore my tabulation of the Groups of Paropsis 

 w^ill stand as follows : — 

 A. Sides of the prothorax mucronate in front, or sinuous about 



the middle, or both Group i. 



AA. Sides of the prothorax evenly arched. 



*B. Puncturation of the elytra non-seriate, or only partially 

 seriate through the presence of unpunctured longitu- 

 dinal spaces Group ii. 



BB. Elytra seriate punctulate in about 20 rows. 



C. Elytra verrucose Group iii. 



CC. Elytra non-verrucose Group iv. 



+BBB. Elytra seriate-punctulate in 10 rows Group v. 



In the former parts of this series of memoirs I have dealt with 

 Groups iii., iv. and v. (the last being there called Group vi., as 

 explained above), which contain by far the larger part of the 

 species of the genus. I now offer a memoir completing the work, 

 and begin with 



Group i. 



The character by which this aggregate is distinguishable from 

 all the rest is the peculiar shape of the prothorax, the lateral 

 outline of which is not evenly arched (as it is in the other groups), 



* This aggregate comprises Groups ii. and v. of my former tabulation 

 {loc. cit.). 

 t This aggregate stands as Group vi. in my former tabulation {loc. cit.).
