46 THE ENTOMOLOGIST’S REOGORD. 
were busy eating the pollen, as far as I could see, but I managed to 
lose sight of the dozen or so I caught, so I can hardly say I know what 
they are. In the field I considered them Microptery« seppella, Fab. 
Mr. Case, a local entomologist, obtained Melitaea aurinia regularly, but 
I missed the locality owing to working on too small a scale map. The 
same gentleman obtained Manduca (Acherontia) atropos here on Sep- 
tember 2nd, 1914, and Limenitis sibilla in 1917 at Four Ashes, quite 
near to Broadwinsor. 
Mr. A. E. Webber has also taken Argynnis cydippe (adippe) and 
Hamearis (Nemeobius) lucina here. Witb regard to the Melitaea aurinia 
this locality was on the Greensand and Gault I now know. 
Powerstock.—This village lies below the 500 contour line, just 
under Drake North, on the Inferior Oolite. There is a profusion of 
Lotus corniculatus and Anthyllis vulneraria. I passed through it once 
and obtained Pararye aeyeria var. eyerides and Polyommatus icarus. It 
will be noted that although var. egerides descended as low as the Lower 
Lias, I never obtained it higher than the Inferior Oolite, nor did I 
obtain it in woodland. 
Poorton.—This is a district rather than a village, mostly above 400 
feet and below 500 feet, lying south of Hooke Park and south-west of 
Drake North. It is nearly all Inferior Oolite, and in the shady lanes 
I looked in vain for Leptosia sinapis, which Mr. Webber used to obtain 
there sparingly in the early 1880’s. I found P. aegeria var. eyerides 
fairly frequent, also Melanthia ocellata. | also found two empty cocoons 
and one pupa (unfortunately ichneumoned) of Cerwra bifida. In this 
district I crossed a small area of Great Oolite, and there I got a 
solitary Aricia medon (astrarche), an interesting capture, as Mr. Webber 
and Mrs. Hudson both record the insect as more nearly common at 
Bothenhampton Quarries, also on the Great Oolite. Pyrameis cardua 
was careering wildly about, and I got a single Cosmotriche (Odonestis) 
potatoria. Mr. Webber records Callophrys rubi. I did not see it myself, 
but Poorton was only taken en route for Drake North, and the exami- 
nation was casual. 
That practically finishes the high ridges to the north of Bridport. 
Poorton is strictly independent of the high ridge from Lewesdon to 
Drake North, but has the appearance in the distance of being a secon- 
dary ridge of foot hills. 
Dorrzry.—A bout five miles from Bridport, on the Lewesdon Road, 
is a village of this name on the Middle Lias. I merely passed through 
it, capturing Heliaca tenebrata, which was dancing about the hedges, 
and taking a single larva of Lasiocampa quercus. It will be noted that 
this was the lowest horizon I obtained H. tenebrata upon. 
Atiineton.—A small hill just outside Bridport, to the west. It has 
a capping of Inferior Oolite, and is just over the 200 foot contour. It 
has the appearance of having been entrenched at some time. Here I 
got Huchloé cardamines, which is a really common insect round Brid- 
port. Polyommatus icarus was abundant, and included a fair number 
of @ ab. caerulea. Aricia medon (astrarche) was not uncommon but 
over, and I was only able to pick one presentable specimen. It will be 
observed that Inferior Oolite is a calcareous rock. Huclidia mi was 
abundant, Pararye megera in evidence, whilst E'pinephele jurtina (ianira) 
was just emerging. Zyyaena filipendulae was present but not common. 
I obtained two. Having regard to the time of emergence, the width of
