No. 425.] THE TEXAN LEGIONARY ANTS. 369 
There can be no doubt that this histerid is a true myrme- 
cophile of Eciton opacithorax Em., for Wasmann mentions it as 
occurring in North Carolina near a nest of the same ant.! 
6. Echinodes setiger Lec. 
We have found this histerid in company with Eciton caecum, 
although very rarely. It is not uncommonly seen, however, 
in nests of Solenopsis geminata Fabr. and various species of 
Pheidole. 
HYMENOPTERA. 
PROCTOTRUPID/E. 
7. Ceraphron croceipes sp. nov. 
Female. Length 1 mm. Black, shining, feebly punctured. Antenne 
ten-jointed, black, scape ferruginous except at tip, where it is darker ; 
pedicel pale at tip, constricted towards base, one and one-half times as 
long as first flagellar joint; second joint as long as first but stouter, not 
transverse; 3-5 equal in length, but gradually wider; 6 and 7 broadest, 
subequal, quadrate; last joint as long as two preceding, and as wide at 
base, acutely conically pointed at tip. Head finely punctured and white 
pubescent. Frontal cavity deep, circular in outline, bare, and impunctured. 
Groove in front of anterior ocellus punctiform. Mandibles dark yellow, 
palpi pale. Collar black, with a lemon-yellow stripe on each side. Thorax 
very delicately punctulate and white pubescent; mesonotum with a small 
tooth at each anterior angle. Axille broadly meeting in front of the scutel- 
lum, which is one-half longer than wide and fringed with stout golden 
bristles on the sides, except near the apex, its sides strongly areolated ante- 
riorly. Postscutellum rounded at tip, its sides sinuate and white pubescent. 
Metathorax polished, its posterior angles produced and carinate. Meta- 
pleure smooth, obliquely striolate behind, and bounded by two carine 
above. Tegulz piceous, wings subhyaline, slightly infuscated toward apex. 
Abdomen polished black, the second segment twice as long as the follow- 
ing segments, coarsely striolate at base, with a tuft of white pubescence 
at each anterior angle. Third and fourth segments about equal, fifth and 
sixth shorter and equal. Legs, including cox, wholly deep yellow, except 
the apical joint of all the tarsi, which is piceous. Posterior coxe with a 
bunch of yellow hairs posteriorly. 
Described from a female specimen collected in the galleries 
of a nest of Eciton caecum Latr, at Austin, Texas, Feb. 3, 1901.
