D. C. Timins (Proc. Ent. Soc. 18G7, pp. ci-ciii) notices the species of the 
genus Thais f of which he admits 7, namely : — T. cassandm (Boisd,) sshijpsi- 
pijlc (Iliihn.) ; T. hypsipylc (J3oisd.) = ;?o/7/.rcnflr (Ochsenh.) ; T. caucasica] 
T. cerisyi] T. medecicasta = rumina (\l\xhn.) = rimmia-aiistralis (Esp.), var. 
— honnoratii (Boisd.) ; T. rumina and 1 new species.

Pierides. 
Herrich-Schapfer (Corr.-Blatt zool.-min. Ver. Begensb. xxi. 
pp. 100, 124, and 138) bas continued his Prodromus of a System 
of Lepidoptera through this subfamily. He discusses the cha- 
racters of these insects, and tabulates the genera, which he ad- 
mits, 27 in number, on pp. 103-105. Of these genera 5 aj)pcar 
to be new. The species belonging to this group arc catalogued 
by Hcrrich-Schaffer [l.c. pp. 106, 124<-128, and 138-144). 
A. 11. Wallace (Trans. Ent. Soc. 3rd ser. iv. pp. 301-416) 
publishes an account of the Pierides of the Indian and Austra- 
lian regions. In the introductory portion of this memoir, he 
discusses the general geographical distribution’ of the Insects of 
this subfamily, in which he recognizes 23 genera. Following 
Sclater’s division of the surface of the globe into six zoological 
regions, he indicates that the genera of Pierides are represented 
in these in the following proportions : — Neotropical 11, Nearctic 
6, Palaearctic 6, Ethiopian 10, Indian 15, and Australian 11. 
The South- American continent has 3 peculiar genera, the In- 
dian region 2, and the Australian and Palsearctic regions 1 each. 
PieriSj as stated by Wallace, is the only genus universally dis- 
tributed ; but Colias is likewise represented in all the six regions, 
although in warm climates chiefly confined to alpine districts. 
The whole of the facts connected with the general geographical 
distribution of the Pierides are summed up in an excellent 
table (p. 303). 
Wallace has maintained that the eastern archipelago may be 
divided into two parts, as evidenced by the distribution of its 
Birds and Mammals. These two parts are separated by a line 
passing to the cast of the Philippines, curving round the west of 
Celebes, and afterwards passing between the islands of Baly and 
Lombock. The islands to the west of this line arc regarded as 
belonging to the Indian region, and those to the cast of it to 
the Australian. Pascoc has stated that this rule docs not hold 
good with regard to the Coleoptera, and especially the Longicorn 
Beetles. Wallace indicates some points in the geographical dis- 
tribution of the Coleoptera which seem to confirm his previous
