104 ENTOMOLOGICAL NEWS. [Mar., '18 



Nemobiits in the collections. The color pattern is, however, 

 distinctive, while the excellent characters for the Group Nem- 

 obiites prevent any possible confusion with the species of 

 Miogryllus. 



Type: 9 ; Berkeley, California. November 18 to 20, 1906. 

 (J. C. Bradley.) [Hebard Collection, Type No. 472.] 



Size large for the genus, larger than any of the North American 

 species except A r . (Argizala) brasilicnsis (Walker) ; form very ro- 

 bust; surface shining; head and pronotum with hairs reduced in num- 

 ber. Head large, very full and rounded, about as wide as pronotum, 

 width slightly but distinctly greater than depth. Ocelli subobsolete, 

 indicated by inconspicuous minute spots, the surface at these points 

 showing no convexity. Eyes slightly less ample in proportion to size 

 of head than in other North American species. Maxillary palpi as 

 normal for North American species. Pronotal proportions interme- 

 diate between those of pantcli and brasilicnsis, length distinctly more 

 than half of width. Tegmina much reduced, very slightly longer than 

 pronotum, slightly the more produced at humeral angle, the margin 

 there broadly rounded, the distal margin thence weakly oblique to 

 the very broadly rounded sutural angle ; longitudinal veins con- 

 spicuous, cross-veinlets very few. Wings probably absent. Ovipositor 

 very short and heavy, about as long as caudal metatarsus, straight." 

 Subgenital plate small, scoop-shaped, the free margin divided into 

 two evenly convex portions, the juncture of which forms a median 

 acute-angulate emargination. Caudal tibia with four internal and 

 four external dorsal spines, which are rather short and heavy for 

 the genus, much as in pantcli: these have their ventral surfaces con- 

 cave, with margins microscopically and very minutely serrulate. Cau- 

 dal tibia with three pairs of distal spurs, of which the ventral pair 

 are unequal in length ; longest, dorso-internal spur, two-thirds as 

 long as metatarsus. 



Length of body 10., pronotum 1.95, exposed portion of tegmen 2.15, 

 ovipositor 2.35, caudal femur 5.5, caudal tibia 4.2. Width of head 3., 

 pronotum 3., dorsal field of tegmen 2., abdomen at widest point 3.3, 

 caudal femur 2.1 mm. 



General coloration shining mummy brown and ochraceous-orange. 

 Head with occiput ochraceous-orange, washed with mars brown 

 caudad of lateral ocellar areas and between these flecks, mesad, sup- 

 plied with three nearly attingent smaller flecks of the same color; 



2 The valves are distorted distad, each separating from the others, 

 as has been observed in other species of \anobius (see Hebard, 

 Proc. Acad. Nat. Sci., Phila., 1913, p. 453, footnote 51, [1913]), and 

 are apparently much worn, no trace of teeth being found.
