19. Formica picea; worker. Tex. 
According to Mayr (’86, p. 431), who saw some of Buckley’s types, 
this is Prenolepis vividula , Nyl. (-P. parvula, Mayr, according to 
Emery). I have not yet been able to find the true P. parvula about 
Austin (Buckley’s type locality), nor, indeed, anywhere in Texas, but 
instead I have often found a very closely allied form which Emery’ (in 
lift.) regards as an undescribed species (see, however, Buckley’s F. ter- 
ricola, No. 28). I believe that it would be best to accept Mayr’s synon- 
omy or to discard Buckley’s name and description altogether. 
20. Formica Lincecumii; male, female, worker. Tex. 
Emery (’94, p. 338) believed that this might prove to be a species of 
Formica , but no such tree-inhabiting Formica is known to me to occur 
in Texas. Buckley may perhaps have had specimens of a Dolichoderus , 
D. Taschenbergi, Mayr., e. g., which should occur in Texas, as it is 
known, to occur in Louisiana. Unfortunately, only the worker of D. 
Taschenbergi is known, so that the description of the male and female 
of Buckley’s species can not as yet be utilized in the determination. 
Buckley’s form could be identified as Camponotus ( Golobopsis ) impres- 
sus , Bog., which lives in trees, were it not that he expressly mentions 
the presence of a discal cell in the female, and could scarcely have over- 
looked the peculiar configuration of the head in this sex. 
21. Formica festinata; female, worker, soldier. Tex. 
This species is recognizable with certainty as a variety of Campono- 
tus fumidus, Bog., of very common occurrence on the dry hill-slopes of 
Central Texas. It is characterized by the absence of hairs on the anten- 
nal scape of the worker major.* This is such a large, conspicuous and 
widely distributed ant that Buckley simply could not have overlooked 
it. Moreover, his ethological notes are reasonably correct and apply to 
no other species in the State: “They are very active, traveling beneath 
rocks and sticks where they have cells and galleries in the earth to a 
depth of twelve or eighteen inches. They are not war-like, and rarely 
bite when caught, nor are they often seen in the open air, hence they 
probably seek food by night.” A good instance of Buckley’s superfi- 
ciality as an abserver is shown in his supposition that the dark-headed 
workers major are simply older individuals than the slender honey-yel- 
low minors. The Central Texas form of C. fumidus may be known as 
var. festinatus, Buckley. 
22. Formica insa?ia; female, worker. Tex. 
This is undoubtedly a synonym of Dorymyrmex pyr amicus, Boger. 
Besides the fact that the description agrees well with the commoner 
*In Trans-Pecos Texas this form is replaced by another variety ( fragilis Per- 
gande or pubicornis Emery).
