6 WHEELER. [VOL. II. 



worker-like aspect. These were seen only twice --once in a 

 large nest found under a log on March 12, and again in a nest 

 discovered in a very different locality by Mr. Brues, March 31. 

 In both nests there were many of these winged females 

 resembling Fig. 2, 9. They had small but distinct ocelli. 

 Several of them had lost some of their wings, while a slight 

 touch caused others to lose these appendages. Before finding 

 these winged females, I had found the winged males as early 

 as March 3 in a small nest containing ergatoid females and 

 workers. There were two of these males clinging to the 



o o 



under surface of the stone that covered the surface galleries 

 of the nest. They differ so much from the apterous females 

 and workers, that, if taken on the wing, they would scarcely be 

 regarded as ants (cf. Fig. 2, $, and Fig. 3). They are much 

 shorter and more slender than the workers, and their long, 

 slender, 13-jointed antennae are not geniculate, but straight, 

 with the basal and second joints short and the remaining 

 joints slender and subequal. The eyes and ocelli are very 

 large and prominent. These and other equally pronounced 

 structural peculiarities in the thorax and abdomen are shown in 

 Fig. 2, $. The small mouth-parts, the hypopygium, trochanters, 

 tibiae, and tarsi are honey-yellow ; the venter and sides of the 

 abdomen are piceous. 1 On the 3ist of March I found four 

 nests containing winged males. Three of these nests each con- 

 tained three males, the remaining nest contained only two. 



L. elongata is smaller and far more slender than P. Jiarpax, 

 with long delicate legs and antennae. The specific name is 

 very applicable not only to the adult ant but also to the egg, 

 larva, and pupa. The worker (Fig. 4, 9) is of a rich claret red 

 color, becoming yellow towards the tip of the abdomen. In 

 form, color, and movement this ant is certainly the embodiment 

 of elegance. The workers which were dissected --some thirty 

 specimens from different nests --contained only minute and 

 abortive ova, and for some time I failed to find the queen. 



1 To my knowledge no description has hitherto been published of the male of 

 the typical P. harpax. I infer, however, from Forel's contribution (loc. cit., p. 12) 

 that Smith has described (Cat. ffym., vol. vi, p. 108, 1858) the winged male of his 

 P. monteziimia, a form which Forel regards as merely a Mexican race of P. harpax.
