2 PROCEEDINGS OF THE NATIONAL. MUSEUM. vol.64. 



Head, entire thorax, and antennae ferruginous, propodeum piceous 

 stained; front and middle legs piceo-testaceous ; hind legs darker, 

 their coxae nearly black; wings hyaline, veins and stigma blackish, 

 the latter whitish at base ; abdomen black, second tergite with a trans- 

 verse yellowish band at base, from which lines of the same color 

 project obliquely toward the posterior lateral corners, all tergites 

 very narrowly golden at apex. 



Male. — Aside from the usual sexual differences in form, differs 

 from female practically only in having the propodeum and meta- 

 pleura more strongly rugose and black. 



Host. — Chrysopa lateralis Guerin. 



Type locality. — Little River, Florida. 



Type.—C^t. No. 25914, U.S.N.M. 



Described from two females and one male reared from host on 

 avocado by G. F. Moznette, and received from the Bureau of Ento- 

 mology, United States Department of Agriculture. 



The paratype female has the propodeum darker than in the type 

 and the yellow- marking of second tergite better defined. 



ARACHNOLETER, new genus. 



Because of the short fourth joint of the maxillary palpi in com- 

 parison with the fifth joint, together with its agreement with the 

 characters leading up to this point in the key, the genotype runs in 

 Schmiedeknecht's Genera Insectorum key to Hemitelini to Blapsi- 

 (lotes Foerster, a genus without included species. 



Head transverse; temples receding to the very strong and com- 

 plete occipital carina; eyes and ocelli small, the malar space and 

 ocell-ocular line long; face short; clypeus separated, strongly ele- 

 vated in middle, with a narrow reflexed margin; mandible with a 

 strong transverse ridge at base; antennae filiform, slightly thicker 

 beyond middle, basal joints long, first longer than second. Thorax : 

 notauli strong, extending two-thirds the length of mesoscutum; 

 scutellum convex, without carinae; sternauli strong and complete; 

 prepectal carina extending to subalar tubercle; propodeum com- 

 pletely areolated, apophyses not prominent; legs slender; calcaria 

 short ; areolet open, the second intercubitus weakly indicated, cubitus 

 abruptly weak beyond areolet; radial cell short, hardly as long on 

 metacarpus as stigma, radius originating far beyond middle of 

 stigma; nervulus inclivous and lower abscissa of postnervulus re- 

 clivous, so that brachial cell is shorter on brachius than on discoi- 

 deus; abscissula shorter than intercubitella ; nervellus broken at or 

 below middle. Abdomen: first segment narrow throughout, post- 

 petiole parallel sided, dorsal carinae strong to apex, spiracles in 

 middle; other segments together broadly ovate; ovipositor sheath 

 shorter than first tergite.
