32 THE ENTOMOLOGIST S RECORD, 
in the R. Stazione d’Entomologia Agraria, there exists a very inter- 
esting specimen labelled: ‘ Valenzia,’’ which I must take this occasion 
to mention. It is quite similar to nymotypical sorrentina, as described 
above, but each one of the six spots of the forewing is surrounded by a 
white ring; this character is extremely rare and never so marked in 
Italy. Does transalpina, then, occur in Spain and does it produce 
quite a distinct race ? 
The races of group b hereunto described are the two following : 
Race maritima, Obth.—Similar to emendata, but with brighter 
colouring and with the dark scaling tending to expand; red spots. 
smaller; the sixth often absent; hindwing with a broad dark margin; 
sometimes very broad and never as narrow as in emendata; red patch 
of underside forewings always narrow and occasionally entirely absent. 
This is the race of the south of France, which extends in Italy, along 
the Riviera, as far as is known, up to Genoa. 
Race transiens, Rocci.—So called because in extreme specimens the 
dark scaling is as extensive as in sovrentina, invading the whole dorsal 
margin and anterior portion of the hindwing, and thus believed to be 
a transition from maritima to sorrentina. This view however is not 
correct, for the structure of transiens is even more robust than that of 
maritima, Whereas areal transition to sorrentina should come nearer 
the frailer build of the latter. The right way of putting it is that 
transiens stands to maritima as sorrentina stands to altitudinaria or 
intermedia, being the most melanotic race of the robust maritime 
group. Rocci says at Genoa it flies quite near the sea, lower than 
maritima. The race, found by Querci at Formia, in the province of 
Caserta, at low altitudes and considered as maritima by Oberthiir and 
Turati, has turned out to be identical with transtens on comparison with 
a series from Genoa sent to me by Rocci. 
I think the following diagram will help to clear the connections 
between the different races, if it be borne in mind that the robustness 
of their structure increases from above downwards and the extent of 
dark scaling from left to right :— 
occidentalis—loti altitudinaria 
centralis inter media—sorrentina—latina—calabrica 
emendata 
alpicola maritima—transiens
