Black ; palpi, flagellum, abdominal segments 1 — 3, belly, and 

 legs, rufous ; hind tibiae at the apex, and their tarsi, more or less 

 infuscated; claws black. Wings fusco-ferruginoiis, the basal half 

 and the radial areolet more testaceous ; 1st abscissa of the radius 

 clouded; squamulae, nervures, and stigma fuscoiis, the last at the 

 inner angle determinately luteous. Head and thorax thickly 

 punctulate, but somewhat shining ; scutellum smooth ; metathorax 

 rugose, with or without a medial carina. Segments 1 — 3 rugulose ; 

 1 subquadrate, its basal angles rounded, with an impression between 

 them, the apex truncate; 2 transverse, longer than 3, both feebly 

 carinated in the middle ; the rest smooth and shining. Terebra 

 hardly I of the abdomen ; valves subclavate. Inner spur of the 

 hind tibiae half as long as the metatarsus. ^ ? . Length, 2 — 2i ; 

 wings, 4 — 5 Im. 



Antennae $ as long as the body, the two basal joints black ; 

 flagellum mostly fusco-ferruginous, the apex sometimes testaceous. 

 Those of the <? are 4 lines long, and much darker. Face and 

 clypeus granulated, dull; mandibles ferruginous, darker at the 

 tips. Mesothorax depressed in the middle, and there almost rugu- 

 lose, with vestiges of the thoracic sutures. Pleurae and pectus 

 punctate, the former smooth above the usual fovea. Abdomen $ 

 longer than the thorax, depressed, with parallel sides; of the J 

 shorter and more rounded ; the apical black segments taken 

 together are not so long as the 1st segment. The wings of the c? 

 are lighter than those of the J , which latter have a deeper stain 

 beneath the stigma. 



The most conspicuous species of this subfamily, and 

 rare ; the British Museum contains one male from Haliday 

 (Ent. Soc. Coll.), two males and one female from Stephens' 

 collection, and three males from that of Desvignes. 

 Euthe had inspected five males and two females from 

 Berlin, Danzig, and Oranienburg ; Wesmael captured a 

 male near Brussels, and two others are recorded by 

 S. V. Vollenhoven, taken at Eotterdam and the Hague. 

 Haliday found both sexes very scarce on the muddy
