Euglossa cordata, Linn. Mr. G. W. Sworder told me that in Tobago 
Euglossa specially frequents the flowers of the Orchid, Coryanthes 
maculata punctata, Lindl. The structure of the Orchid is remarkable, 
and so is the length of the proboscis of the Bee, and doubtless there 
is a relation between them. 1 
The commonest Wasp was the large Polistes annularis , a dis¬ 
tinctly formidable-looking animal with a pale cream-coloured band, 
but dusky-winged; of P. subsericeus, Sauss., I got but one; there 
was also an unnamed Polistes, a large insect with dark wings and pale 
tarsi. Of Polybia there were several species; P. nigra, Sauss., P. 
angusticollis, Spin., and P. occidentalis, Oliv., the latter obtained by 
sweeping, but none of them were common. Of Odynerus I took a 
single specimen, a female. The Social Wasps of the genus Zethus 
were represented by the greyish-black, pur pie-winged chalybeus, 
Sauss., and by another species unnamed, of which the British 
Museum possesses an example from Nicaragua; it is allied to Z. 
hilarianus, Sauss. There were also two of another social wasp, 
Synoeca cyanea, var. ultramarina. I captured three of the somewhat 
dingy, long-waisted Mischocyttarus labiatus, Fabr., var. drewseni, 
Sauss., and one of a Sphex of the genus Oxybelus. The harmless Ant, 
Camponotus rufipes, Fabr., was frequently seen. 
I had little time to give to Bugs or Beetles, and therefore naturally 
only took such as obtruded themselves on my notice. A Lygaeus 
nearly allied to circumlatus, Stal, had no representative in the 
National Collection. Another bug of the same family, Dysdercus 
ruftcollis, Linn., was taken on the wing. Euchistus bigibbulus was 
a Jamaican acquaintance. 
Curiously enough only one solitary Beetle came in my way. This 
was a Dung-beetle, a species of Canthon, which Mrs. Longstaff found 
in the water of a tank near the above-mentioned farm; it was of a 
species not represented in the British Museum. This, with a very 
elegant Demoiselle Dragon-fly having carmine patches at the base of 
the wings (near to Agrion brightwelli, Kirby, and caja, Drury), com¬ 
pletes my list of captures in the best locality that it has been my 
good fortune to visit. 
Close by the Ithomiine swamp was a small cave which I entered 
in the hope of finding Lepidoptera at rest, but did not see any living 
creatures save crowds of bullet-bodied, long-legged Harvestmen 
(Phalangium). I have never before or since seen any approach to 
such a number of these animals together. 
There is a difference in the meaning of the word “ grand ” in
