to the preceding joint, but one-third longer, subequal in length to the pedicel, 

 and nearly a third larger than funicle 3 ; funicle joint 3 shorter, equal in length 

 to funicle, 1, or somewhat longer, and cylindrical oval, therefore somt what 

 thicker than the preceding funicle joints; funicle gradually thickening from the 

 third joint to club; funicle joints 4 and 5 subequal in length and width, oval, 

 thicker than the joint immediately preceding but somewhat shorter, nearly 

 equal in length to funicle joint 1 ; funicle joint 4 very slightly longer than joint 

 5 of the funicle, the latter not as large as in the figure. Club imdivided. abruptly 

 longer and broader, with 2 paler furrows visible from one side; it is as long as 

 the three preceding joints combined, and about twice the length of the scape, 

 and ovate in shape, the base rounded, the apex tapering; club uniformly hairy. 

 Antennae bearing rather sparse soft hairs beyond the second joint of the funicle, 

 most numerotis on the club, but sparser on funicle joints 1 and 2; scattered on the 

 pedicel and scape; in general a single whorl on ftmicle joints 1 and 2, and 2 on 

 oints 3-5 of the funicle, and more or less uniform on the club. (Fig. 3). (From 

 39 specimens. 2-3 inch objective Batisch & Lomb.

The same. Antennae 10-jointed, filiform; scape and pedicel the same, the 

 first fimicle joint, however, a Httle moi-e than half the length of the pedicel, 

 and the second funicle joint, or nearly two-thirds the length of the latter; funicle 

 joint 3 a Httle longer than the second joint, funicle 4 about 1-4 longer, and thicker 

 than funicle 3; funicles 4, 5, 6, and 7 subequal in length and shape, and trun- 

 cate, slightly wider anteriorly and bearing a thicker seta from each apical corner; 

 preceding joints cjdindrical; club or apical joint conical, shorter than the preced- 

 ing funicle joint.^ Antennae thickening tiniformly beyond the thirci funicle 

 jofnt; flagellum, excluding the scape, apparently longitudinally striate; clothing 

 as in female, the hairs slightly more sparse in the male. (From 2 spe'-'me^-'s.

Described from two males and thirty-nine females mounted in 

 balsam. The species is larger than globosicornis, lighter in color, 

 and the antennae entirely different structurally. Otherwise they 

 are superficially alike. I have before me the following specimens 

 kindly transmitted by Dr. L. O. Howard: Six slides marked: 

 "Morrill No. 2009. Bred from Psocid eggs, Orlando, Fla., VIII, 

 5, 1907. E. A. Back" (3 slides, 14 females); "Morrill No. 2002.
