MACKOCEKEl COILA n.g. 



This genus is founded on the male alone, the female still being 

 unknown, but is easily recognized by its long sixfeen-jointed antejinie, 

 about twice as long as the whole insect; the third joint is much 

 shorter than fourth, while the following joints are four times or more 

 than four times as long as wide ; the scutellar cup is very high, 

 deeply excavated, wath the margins sharp and slightly deflexed. 

 The apical tibial spur on anterior legs is very long, curved, and there 

 is a distinct cidiital nervure extending from the obsolete areolet to 

 near the apical margin of wing ; nieso- and metapleuraj smooth, 

 polished. 



No S parasitic cynips has been described with more than 14—15- 

 jointed antennae, and while not uncommon among the gall-making 

 cynips, the 16-jointed anteunifi makes the following species a unique 

 among the Figites : 



47. Macroforeiicoila loiigiooruis n. sp. — %, . Length .10 inch. Black, 

 polished; the sixtceu-jointed antennie and legs including coxse, red. Wings 

 hyaline, pubescent, veins reddish, radial area large, closed ; cubital cell partly 

 closed, no areolet.

48. Eucoila rubripes n. sp.— '^ . Length .10 inch. Similar to the above 

 but with only fifteen joints in the antenne and the wing veins not reddi.sh but 

 pale, and the cubital nervure is not at all developed. 



Described from two specimens.
