1910] Wheeler — Mites of the Genus Antennophorus 5 
female is much longer and very different in outline and the anoventral 
scute is less tapering in front. 
Several of the female specimens of A. donisthorper each contain a 
single, large, mature egg, as shown in Fig. 3. This seems to indicate 
that Antennophorus, unlike many other mites and the ticks, is in the 
habit of producing only one egg at a time. This egg is perhaps at- 
tached to the surface of the ant which is infested by the mite. 
Antennophorus wasmanni sp. nov. 
Male. (Figs. 10, 11, 12, 13 and 15.) Body very convex above, nearly 
as broad as long, very broadly oval, distinctly wider behind than in front, 
with its anterior and posterior ends very obtusely angular. Upper surface 
smooth and shining, polygonally areolated under a high magnification, brown, 
without a darker vitta or perceptibly paler central area, and covered with 
longer, more slender and somewhat sparser hairs, than the preceding species. 
Legs and scutes of the ventral surface brownish, remaining portions yellowish. 
Legs decidedly longer than in A. donisthorpei, coxze and trochanters of three 
posterior pairs not laciniate-denticulate. Hairs on these pairs of legs very 
long and straight. Anoventral scute broad in front, connected with the ster- 
num by two slender bands which enclose the genital orifice. Chela very long; 
digits slender, subequal, the fixed one simple but not spatulate, its tip curved, 
blunt and finger-like; the movable digit with a hooked, pointed tip and a 
flattened, lobular process (adnate spur) on its outer side. 
Length: 900 4; breadth: 830 p. 
Female. (Figs. 14, 16,17 and18). Resembling the male in form and color- 
ation but somewhat larger. Body broader than long. Sternum larger, sub- 
elliptical, median, entire and apparently nude. Anoventral scute short, sub- 
cordate, with a rapidly tapering anterior process that terminates between the 
genital scutes. The latter resemble those of the preceding species and A. 
foreli. Hairs on the anoventral scute very short and sparse. Chela with 
subequal digits, each terminating in a hooked point, their inner borders armed 
with larger denticles than in the preceding species and one large tooth on the 
movable digit. 
Length: 990 4; breadth 1040 pu. 
Described from two males and two females taken May 22d, 1909, 
on the Faulkner Farm at Forest Hills, Boston, Mass., with workers 
of Lastus umbratus Nyl. var. aphidicola Walsh. ‘The mites were not 
seen till after they had been killed in alcohol with their hosts. 
This species is dedicated to the Rev. E. Wasmann, S. J., who has 
contributed so much to our knowledge of the myrmecophilous insect 
of all lands. It may be readily distinguished from the preceding 
species by its much more convex dorsal surface, longer legs, the longer
