Psyche 
[March 
female of lineolata or of any of its various subspecies and 
varieties, but the male has departed so little from that of its 
host, that its characters are rather elusive. This is not sur- 
prising since the male is the conservative sex among the 
Formicidse. 
Crematogaster (Acrocoelia) kennedyi sp. nov. 
Female. — Length 5-6 mm. ; forewing 5 mm. 
Decidedly smaller than the females of lineolata , its sub- 
species laeviuscula Mayr, coarctata Mayr, etc., which meas- 
ure 8-9 mm., w T ith the anterior wings 7-7.5 mm. Head 
less narrowed anteriorly and more rectangular, owing to 
the sides being straight and the posterior corners less 
rounded. Antennse longer, the scapes extending a distance 
equal to their greatest diameter beyond the posterior cor- 
ners (not reaching the posterior corners in lineolata). 
Thorax shorter and stouter, the mesonotum being nearly as 
broad as long (decidedly longer than broad in lineolata) , the 
epinotal spines more acute and acuminate, and the base of 
the epinotum external to the spines conspicuously swollen. 
Dorsal surface of petiole more convex, with straight instead 
of concave anterior border, its sides less converging poste- 
riorly; postpetiole more broadly grooved or impressed in 
the middle behind. Gaster much shorter in proportion to 
its width, less parallel-sided, more subtriangular and there- 
fore more like that of the worker lineolata. Legs rather 
short. 
Even smoother and more shining than the subsp. laevius- 
cula. Mandibles coarsely striato-punctate. Head very finely 
striated anteriorly, rather sparsely and finely punctate be- 
hind; thorax and gaster with similar but even sparser 
punctures; mesopleurse and sides of epinotum less shining 
than the mesonotum, scutellum, postpetiole and gaster, 
longitudinally rugulose ; petiole subopaque, very finely 
granular. Antennal scapes and legs distinctly punctate. 
Hairs glistening, yellowish, erect or suberect, much more 
abundant, much shorter and of much more even length 
on the head, thorax and gaster than in lineolata, and con- 
spicuously long and abundant on the petiole and postpetiole.
