Walker’s record of Nova Scotia, and especially Newfoundland, indicates 
that it even enters the Boreal. I have recently found it in the Rio 
Grande valley at Las Cruces, N. M. 
14. Jurinia apicifera Walk. — June 21 to 28. On flowers of Lippia 
lanceolata Michx. Extends from the Transition and Appalachian to the 
Neotropical. 
The following are two species, recently determined, of a small lot of 
characteristic maritime diptera, belonging to the Mexican Maritime 
fauna (Antillean), taken on the south end of Padre Island, opposite 
Point Isabel, Texas. 
15. Tabanus maritimus Towns, n. sp. — June 29, 1895. A whitish 
species found on logs and sand, on the beach. Allied to T. psammo- 
philus OS., which belongs to the Antillean fauna of the Florida coast, 
being known from Fort Capron and Lake Worth. 
16. Lipochaeta texensis Towns, n. sp. — June 8, 1895. Occurs numer- 
ously on the moist beach. This very singular fly belongs to the Ephy- 
dridae. The genus, which is quite an aberrant one, has only recently 
been described by Coquillett for an allied species, L. slossonae Coq., from 
Punta Gorda on the Florida coast, and which must belong to the Antil- 
lean fauna of Florida. 
Ants. — The species of ants, hymenopetra, and lepidoptera named be- 
low are all that have so far been determined of the large material col- 
lected in these groups on the lower Rio Grande, and sent to the Depart- 
ment of Agriculture. The ants were examined by Mr. Pergande. They 
are as follows: 
1. Camponotus vicinus Mayr. — Feb. 23. 
2. Dorymyrmex flavus Mayr. — May 2. In foraging parties, climbing 
trees and plants, and in scattered columns on ground. 
3. Tapinoma anale Andre. — March 2. San Tomas, seven miles below 
Brownsville. In earth around cotton roots. 
4. Pogonomyrmex barbatus Sm. — February 23. Swarming out of hole 
in ground. This species is recorded from Texas, New Mexico and Ari- 
zona. 
5. Cremastog aster sp.(?) — February 20. Nest inside dead twigs of fig, 
bored by longicorn larvae. 
6. Pseudomyrma gracilis Fab. var. — February 26 to July. Running 
on vegetation in woods and thickets, especially in the palmetto ham- 
mocks. This is a Neotropical species, which is found everywhere along 
the Mexican coast from the lower Rio Grande to Tabasco, running about 
on vegetation. 
7. Pseudomyrma pallida Sm. — February 23; a winged specimen. Also
