TRINIDAD 
327 
The Pyrale Mageta xanthomelas, Walk., took its place among the 
butterflies, and very conspicuous it was, being especially common 
among Cacao-trees just above St. Ann’s Reservoir. Another Pyrale, 
the silver-grey Glyphodes ausonia, Cram., of which two occurred at 
the highest point attained on the Ariapeta Road, close to the spot 
where I took Euptychia ebusa , was so like that butterfly upon the 
wing, that the two were confounded; yet any one seeing the insects 
side by side in a cabinet would have said that such a thing was quite 
impossible. 
The only other HeUrocera met with in Trinidad were the Hawk- 
moths, Pseudosphinx tetrio , Linn., and Dilophonota ello, Linn., taken 
beneath arc-lights in the streets of Port of Spain. 
I took but very few Beetles: the Longicorn, Stirastoma depressum , 
Linn., distinguished by the hardness of its exo-skeleton, was found on 
a tree-trunk at the good butterfly locality up the Ariapeta path, at 
about 1000 ft. The large orange and black Cantharid, Horia 
maculata , Sweder., and Ligyrus tumulosus, Burm., sought the electric 
lights. Asphaera nobilitata , Fabr., was captured when flying over 
the swamp near St. Ann’s Reservoir. The Elaterid Pyrophorus pel- 
lucens, Esch., captured at night in the Belmont Circular Road, 
exhibited two constant green lights, powerful enough for me to read 
by their aid the smallest print. Under the thorax, in the crack 
between it and the abdomen, was a triangular area which was faintly 
luminous, the light having a slight reddish tinge. Chloroform at 
first increased the brilliance of the green lights, but they were soon 
eclipsed. 1 
The flowers in the Botanic Garden attracted quite a number of 
Bees, mostly small species: Melipona capitata , Smith; M. ruficans, 
Latr.; M. amalthea , Eabr., and M. rufiventris , Lepel., a foxy-coloured 
neatly banded species; Melissod esrufodentata, Smith; Melissoptila sp.; 
the common Honey-bee of the mellifica form. With these was the 
large Bombus-like, yellow-banded, Centris jlavifrons, Eabr., and a 
large blue-black Pompilid. 
The Wasps were represented by a very few individuals: Polistes 
annularis ; Polybia occidentals , Oliv., var. oecodoma, Sauss. At San 
Juan I took Larra gastrica, Tasch., and the very elegant black and 
yellow Sceliphron figulum, Dahl., as well as two Pompilids. 
At the last-named locality I took a Bug, a species of Zicca, which

Sojourn in Jamaica,” p. 106 et seq. By the kindness of Dr. P. L. J.M. de Yerteuil, R.N., 
I was able to exhibit at the Entomological Society a number of living specimens of 
P. noctilucus from Trinidad. Proc. Ent. Soc. Lond ., May 1st, 1907, p. xxxii.
