tennae long, slender, reaching beyond base of abdomen, third joint but little longer 

 than fourth ; joints gradually decreasing in length towards apex ; apex of third and the 

 following joints covered with short, white pile. Head generally covered with small 

 punctures. Thorax punctured like head. First joint of middle tarsi a little longer 

 than 2 + 3 ; posterior coxae a little longer than usual but not as long as in Macrophya ; 

 four anterior legs covered with short white pile especially on tarsi. Intercostal vein a 

 little proximal to the basal ; lanceolate cell of fore wing with a short straight cross- 

 nervure ; second recurrent nervure wanting ; lanceolate cell of hind wings shortly 

 petiolate ; upper discal cell of hind wings greatly exceeding lower on outer mar- 

 gin. Abdomen very minutely punctured at sides above, and two apical segments 

 above the punctures are large and shallow ; apical dorsal segment with a ridge in 

 the middle ; sheath broad, rounded at apex ; apex of abdomen and sheath with 

 rather long hairs. Color black ; spot between antennae, one between antennae and 

 orbit, two spots on the clypeus, labrum, cheeks, an elongate spot on each anterior 

 corner of middle lobe of mesonotum, middle of scutellum, enchri, two spots on side 

 of meso-epimera, a short line on one side of prothorax, middle legs except a line 

 above and tibiae, two lines on posterior coxae, spot on trochanters, a band on hind 

 femora, a more or less obscure line on side of abdomen, pallid ; faint line on inner 

 orbits extending to vertex, where it curves inward, antennae, protibiae and tarsi above, 

 mesotibiae above and mesotarsi dark rufous ; hind tibiae wanting ; extreme apex of 

 apical abdominal segment fuscous. Wings hyaline ; nervures and stigma dark rufous. 



Habitat. — Cameron Pass, Larimer Co., Colo., alt. about 10,300 

 ft., August 3, 1892 (C. P. Gillette). Type in the Colorado Agri- 

 cultural College collection. 



Quite distinct from all the other species assigned to this genus 

 by Rev. Konow (Genera Insectorum). In coloration it resembles 

 Pachyprotasis nigrofasciata but may at once be known from that spe- 

 cies by the more distinct wall around the ocellar basin, the cross- 

 nervure of lanceolate cell, the weaker venation, etc. 

 14. Schizocerus sericeiformis, new species. 



Male. — Length about 5 mm. Cheeks very narrow ; malar space wanting ; 

 clypeus truncate or nearly so, punctured across the middle ; ocellar basin spear- 

 shaped, well defined, walls somewhat rounded ; medial ridge prominent ; a furrow 

 partly surrounding each lateral ocellus above; face depressed around ocelli; antennae 

 short, hardly reaching to scutellum, third joint bifurcate, clothed with rather long 

 black hairs. Scutellum rounded at apex. Claws simple. Lanceolate cell broadly 

 contracted; three cubital cells, first transverse cubital wanting; second cubital (third 

 if first transverse cubital is present) wider on radial nervure than cubital ; transverse 

 median in middle of cell, in one wing there is an extra nervure behind transverse 

 median. Color black, abdomen somewhat brownish ; mandibles and ocelli piceous ; 

 pronotum and tegulae luteous ; apex of femora, tibiae and tarsi (apex of posterior tibiae 

 and their tarsi infuscated) pallid. Wings hyaline; nervures pale brown, stigma and 

 apex of costa a little darker, costa at base pallid. 



Habitat. — Stratton, Nebraska, July 14, 1899 (collector un- 

 known).
