Pygidium broad, marjiined afjically, only its surface with coarse regular and 

 non-confluent punctures; legs and abdomen without red markings. 



maculipes (Mickel) 



Pygidiuin long and narrow, margined throughout, its surface longitudinally 

 rugose; legs and abdomen partly red moestus Cresson

9 . Black, the femora brownish black, the tibiae and tarsi ferruginous; 

 spot beneath fore femora, posterior line and tubercles of pronotum, buff 

 (marguerite yellow) ; apical margin of first five dorsal segments narrowly 

 white (pale olive buff); abdomen with two basal segments, red (burnt sienna), 

 and sides of two or three following. Surface of body covered with consider- 

 able fine white pubescence, giving it a silvery bloom, or in places it is dis- 

 tinctly sericeous. 



Sculpture like that of the male; clypeus with close minute punctulation 

 and scattered slightly larger punctures, front, vertex and dorsum closely 

 and finely punctate; scutellum somewhat rugulose, flat and not margined; base 

 of second ventral segment not prominent nor angled; pygidium margined, 

 finely punctate. 



California: Felton, Santa Cruz Mountains, May 15 to 19, 1907, 300 to 

 500 feet altitude, one female (allotype), two males, (the author), [Cornell 

 University]; Harris, Humboldt County, June 29, 1907, one female, (the 

 author), [Cornell University]; Claremont, one male, (C. F. Baker), [Pomona 

 College]. 



Allotype. — Cornell University no. 133.1. The holotype of this 

 species is in very bad shape, the head being gone and it is very 

 mouldy. The males recorded above agree precisely with the 

 type, as far as it is possible to observe. 



Nysson (Brachystegus) seminole new species 



cf. Black; broad posterior border of pronotum, with tubercles, base of 

 scutellum, spot on outer side of posterior tibiae at apex, broad apical band 

 on first dorsal segment, interrupted band on second, and lateral spots on 

 third, fourth and fifth segments, yellow (maize-yellow); mandibles at base, 

 first three segments of antennae beneath, and legs beyond the trochanters, 

 rufous (mahogany red). Entire body covered with a short white pubescence, 

 which gives it, in proper light, a strong white bloom; front and face strongly 

 silvery-sericeous; wings weakly clouded around their margins. Length, 

 8 mm. 



Front and vertex with strong separated punctiu'es; a weak tubercle be- 

 tween the ocelli, divided by a shallow depression; last segment of antennae 

 curved, obliquely truncate. 



Lateral border of superior surface of pronotum entirely rounded, without 

 angles; mesonotum strongly but not confluently punctate; scutellum with 

 pronounced reflexed lateral margins, longitudinally canaliculate; mesopleura
