WEST INDIES AND SOUTH AMEEICA 
Ancon, about 500 ft. It was so steep that it was quite difficult to 
make one’s way up over the short dry grass, and the heat was intense. 
Under such circumstances it was not possible to get very much, 
especially as the most productive part of the day had passed. Of two 
Papilio polydamas , Linn., and several Euptychia oreba, Butl., seen, one 
of each was captured. A Phoebis was seen but missed. A black and 
red Heliconius in dense scrub was quite inaccessible. The Erycinid 
Mesene silaris, Godm. & S. (which, by the way, was not represented 
in the British Museum) was observed to have a moth-like flight. 
Two females of Terias delict , Cram., were both of the dry-season form ; 
certainly everything on that hot hill was dry enough ! The Skippers, 
which always contributed so largely to the bag, were Eudamus 
simplicius , Stoll; Megistias labdacus , Godm.; Morys Valerius , Moschl.; 
Hesperia syrichthus , Eabr., and H. laviana, Hew. Several of the 
beautiful Utetheisa ornatrix, Linn., were seen among grass. A Wasp, 
Montezumia coerulea, Sauss., was taken as well as Sphex ( Isodontia ) 
costipennis, Spin., and S. nigrocoeruleus , Tasch., which last Mr. 
Eowland Turner says is not a common insect. 
Close to the top of the hill, in a somewhat scrubby wood, a 
procession of “ Parasol-ants,” Atta sexdens , Linn., was seen on the 
march across the path. I could follow them forwards for about two 
yards only where the column was lost in the dense undergrowth, but 
was able to trace them back about 8 yards to a tall tree from which 
they were bringing their “ parasols,” or pieces of leaf much bigger 
than themselves, a fact that may be verified by reference to the Hope 
Collection at Oxford. 
A walk the next morning on lower ground near the railway was 
most disappointing in its results. Danaida archippus put in an 
appearance. I took three females of Precis lavinia , one of them the 
ocellated form, but two were very “ dry,” one of the latter being an 
aberration with very dark hind-wings, almost destitute of any fulvous 
colour; there were also a few P. jatrophae about. Of Terias delia I 
secured two intermediate males, and one dry-season female; as is so 
often found the “ dry ” characters were more marked in the latter 
sex. A pale Hamearis erostratus , Hew., was jthe sole Erycinid, a Cato- 
chrysops hanno the sole Lycaenid. There were but two Skippers, 
the common Hesperia syrichthus, and a male Thymelicus athenion , 
Hiibn. The bug Hypselonotus fulvus, De Geer, was obtained by 
sweeping. 
On our way back at night the Sphinx, Dilophonota oenotrus, 
Stoll, came to the lights of the train at Christobal station.
