A NEW ANT-NEST GOCCID.
BY GEO. B. KING, LAWRENCE, MASS., AND J. D. TINSLEY, MESILLA PARK, N. MEX. The species described below was col-
lected by Mr. King. The notes on the
microscopical characters were prepared
by Mr. King, but have been extended
and rewritten from Mr. King's mounts
by Prof. Tinsley, who is also respon-
sible for the comparison with allied
species. The drawings are by Mr.
Tinsley. The notes on the living insect, and habits, etc., are by Mr. King.
Dactylu$k claviger, n. sp. - Adult 9.
Length 2.5-3.5 mm. Width about z mm.
Sliape, ovoidal, quite plump. Color, dark reddish-brown, covered with white mealy
secretion. Segmentation of body distinct, under hand lens. No lateral or caudal
appendages. Boiled in caustic potash it
colors the liquid a light violet red. Legs and antennae pale yellowish-brown. An-
tennae %jointed ; 8 longest, longer than 64-7, and with several whorls of hairs, the hairs being numerous at the distal end ; I next longest, its diameter equalling or
slightly exceeding its length, a whorl of hairs around its distal end ; a next, its diameter about 4 of its length, two whorls of hairs, one about midway and the other near distal end; 5 next, with two whorls of hairs, one at each end ; 7 next, with a whorl of hairs about its middle, 3 next (3 and 7 are often subequal), its diameter being about 8 of that of 2, a whorl of hairs about its middle ; 4 and 6 about subequal and with a whorl of hairs .
about the middle. The joint between 4 and .i; is often, almost usually, quite indistinct, and this might be considered a prominent characteristic. Antenna1 formula 812573

Habitat, Andover, Mass., Oct. 20, 1896, in the nest of Lasius cznviger Rog. Coil. Geo. B. King; collected again by Mr. King at
Methuen, Mass., Oct. 3, 1897, in nests of Lasiii-s awerkdfl~s Era., "completely con- cealed in ^i round ball of cottony down, attached to roots of grass entering the ants' nest. under a stone " (King).
A striking characteristic of this species is that the antennxe and femora bear numerous long, slender hairs and that the body also bears numerous long, slender hairs. The
relative lengths of the segmentsof the anten- nae are much more constant t.han is usual in ants' nest c.occidft.

most indisting'nishiible from the eastern H. maia except that the head is black. Upper row of spines (i) with short shaft on joints 5-12, an unpaired dorsal spine on joints 12 and 13; none on (lie anal plate; four rows of spines on joints 3 to 6 and 11, three on the other segments. Secondary h~irs ahun- dant, fine, white. Black, head shining;
body thickly covered with small yellow dots, approximate, subconfluent, centered by the secondary hairs. An indicated subdorsal, lateral and broader stigmatal yellow hands, showing as dots in the incisiires which are mostly otherwise free from the yellow dots. Spines black, the basal ones on each shaft i el lo wish. Leg plate black; venter a little reddish.
The yellow dots are less confluent than in H. wain, being especially sparse in the in. cisures. and the stigmatal band is reduced and obsolete centrally on the segments.

liptical, flattened above and below, a little concave; white, shagreened, covered all over with a brown gum, which causes the eggs to adhere to the twig and is applied irregularly, forming darker brown spots and streaks.
Size, 2.6 X 1.9 X 1.6 mm. Hatch by a hole in one end: laid in an irregular mass on a, twig. (11. K. Morrison, Ariz., May 5111, 1883; Coll. U. S. N. M.)
