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

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

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

 sutui'e, somewhat depressed in front of the scutellum; scutelhmi 

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

 length, wholly 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 lly. with pale legs, 

 whitish wings and halteres. Length 2 to 2.2.5 mm. Lapland and 

 Germany ( Beuthin ) . 



Genus 24. Spaniotoma Philippi 

 Verb. z. b. Ges. 35. 620. 1SG5. (P1.37, figs. 13 and 14) 



Thorax prominent above the head. Antennae short, scarcely 

 exceeding the palpi in length, G-jointed, the joints oval, siparsely 

 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 I he 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 fore metatarsus shorter than its tibia. The 

 genus may possibly be synonymous Avith either Metriocnemus 

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



Type S. bivittata Philippi, Chile. No North American 

 species. 



Genus 25. Corynoneura Winnertz 

 Stettin. Ent. Zeitg. 7:12. 1846. (P1.36, fig.7, and pl.32, fig.4) 



Rmall species, distinguished bv the absence of the anal angle 

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