314 THE ZOOLOGIST. 
Colletes americana, Or., Colletes sp. 3 (new to me), Agapostemon 
sp., g, and Calliopsis n. sp. near coloradensis. Also by the 
butterfly Pyrameis cardui and the syrphid fly Chrysogaster bellula, 
Williston. 
1t is thus seen that the visitors observed at these two Composite were 
entirely different. 
Las Cruces, N. M., Sept., Oct., 1895. 
The following collections of autumnal bees have not heretofore been 
reported :-— 
(1). Verbesina encelioides ; Oct. 9th, visited by a 9 Pseudopanurgus 
aethiops (Cr.). 
(2). Aster hesperius, Gray; Oct. 4th, seemed little attractive to bees : 
visited only by <Agepostemon melliventris (Cr.), Bd, anda ¢g 
Halictus. 
(3). Baileya multiradiata; Oct. 23rd, visited by Parandrena rhodo- 
cerata (CkIl.). 
(4). Helianthus annuus; Sept. 21st, visited by Panurginus perlevis 
(CkIl.), Halictoides marginatus (Cr.), in great numbers, Andrena 
pulchella, Rob., Melissodes agilis, Cr., and Podalirius maculi- 
frons (Cr.). 
It is curious that the sunflower Andrena at Las Cruces should be 
A. pulchella, while that at Albugerque is A. heltanth. 
Las Cruces, N. M., Aug. 23rd, 1897. 
In the Larrea zone close to Las Cruces the following were collected by

Mesilla, N. M., Aug. 21st, 1897. 
The flowers of Martynia sp. were observed to be visited by Podalirius 
vallorum, Ckll., 2. On Aug. 19th, at Mesilla Park, P. vallorum 3 was 
visiting a cultivated Chilopsis. The two species of flowers mentioned, 
though of quite different affinities, are not dissimilar in colour and form.
