MEGAMELUS AXIALIS Van Duzee. 

 Plate 49, fig. A. 

 Kelma axialis Van Duzee '97:232.— Osborn '97:235; '04:100. 



Length of body 2.4 mm.; width of vertex 0.22; width of frons 

 0.25; antennae, I, 0.05, II, 0.21. General color brown to dark brown; 

 dorsum and vertex between lateral carinee whitish with vitta appar- 

 ently extending onto anal angles of folded elj^tra ; frons reddish brown; 

 pronotum black at each lateral extremity; tarsi black. Body rather 

 small. 



Head broad, ^vith eyes about as broad as prothorax, broadly 

 rounded in front; vertex a Httle longer than broad, weakly carinate, 

 sHghtly produced in front of eyes: frons roundly hexagonal, less 

 distmctly so than in guttula; median carina almost obsolete at apex 

 of head; cl^'peus small, flat; antennse very short, II about four times 

 as long as I. 



Thorax short, broad; proilotum moderately long behind eyes; legs 

 rather short; calcar typical, large. Elytra short, narrow, reaching 

 a little beyond tip of abdomen, brownish except on both margins 

 subhyaline; membrane small. Hind wings very small, vestigial. 



Male pygofers rather short, typical; styles moderately stout, less 

 acuminate and needle-like distally than in guttula. 



Redescribed from one male and four females from Greensburg, 

 Pennsylvania (Wirtner). This species in some respects is quite 

 similar to the European guttula (Kelisia).
