bare; palpi slightly projecting, bent, proboscis short; eyes round, 

 somewhat prominent, remote; front wide; ocelli wanting; dorsum 

 of thorax elongate, arched, higher than the head, no transverse 

 suture, somewhat dejtressed in front of the scutellum ; scutellum 

 small. Abdomen 7 or 8 jointed. Legs short, robust^ of unequal 

 length, wholl}' bare and unarmed; coxae not elongate; halteres 

 short. Wings as long as the abdomen, club-shaped, rather narrow, 

 bare, with 4 or 5 discal veins diverging apically, all very indis- 

 tinct; on the anterior margin at the apex is a long somewhat 

 curved seta ; the posterior margin is not ciliate. The wings of 

 the female are shorter than the abdomen, the genitalia of the 

 male clubbed, legs more robust; the abdomen of the female 

 pointed, with two short appendages. Metamorphosis and' life his- 

 tory unknown. Translation from Schiner p. 641 (1864). 



The only species of this genus is C. c r a s s i p e s Zett. 

 (=ambigua Zett.), a small, brownish black tiy, with pale legs, 

 whitish wings and halteres. Length 2 to 2.25 mm. Lapland and 

 Germany (Beuthin). 



Genus 24. Spaniotoma Philippi 

 Yei-h. z. b. Ges. 35. 629. 1865. (P137, figs. 13 and 14) 



Thorax prominent above the head. Antennae short, scarcely 

 exceeding the palpi in lenglh, 6-jointed, the joints oval, sjiarsely 

 verticillate with short hairs, the last joint rather acute. Palpi 

 4-jointed, the first joint thickened, the last one slender, elongate, 

 divided (?). 



The wing venation (fig.l3) resembles that of C h i r o u o m u s 

 (sens, lat.) though the crossvein is rather nearer to the base of the 

 wing than in the typical C h i r o n o m u s. The description does 

 not state whether the wing is hairy or bare. The figure given by 

 Philippi shows the foi-e metatarsus shorter than its tibia. The 

 genus may possibly 'be synonymous with either M e t r i o c n e m u s 

 or O r t h o c 1 a d i u s . 



Type S. bivittata Philippi, Chile. No North American 

 species.

 of the wing. Head round, proboscis short, palpi incurved, four-
