»Radial and cubital nervures obsolete. Antennae with the third Joint not more 

 than double the length of the fourth; the other joints not much shorter than the third. 

 Parapsidal furrows obsolete. Metatarsus generaly longer than all the other joints united. 

 Body more or less red. 



Nigra, nitida, punctata, facie, tegulis, pronoto scutelloque rufis; alis hyalinis. 

 cT. Long. 3 — 7 mm. (!) 



Antennae stout, sparsely covered with a silvery-white pile; the basal Joint as long 

 as the following three joints united; the second Joint about one fourth shorter than the 

 third, the latter a little shorter than the fourth; the remaining joints very closely united. 

 Head sparsely covered with a white pubescence; the face coarsely, transversely, rugo- 

 selv punetured, and with a /\-shaped (not very clearly separated) raised part in the 

 centre; the cheeks more closely and much less strongly punetured; front and vertex 

 shining, sparsely covered with shallow, moderately large punetures; the vertex raised in 

 the centre; the eyes slightly diverging and clearly margined. Thorax above bcaring 

 separated punetures like those upon the head; the metanotum more closely punetured; 

 shining; pleurae punetured, the punetures running into reticulations; the sutures striated 

 and shining; the lower part of the mesopleurae shining and impunetate. Petiole shining, 

 longitudinally striolated above. Legs stout, the hind tibiae and tarsi densely covered 

 with a whitish (not bristly) pile. The metatarsus is as long as the following three joints 

 united; the spurs pale, the longer one reaching to the middle of the metatarsus. All the 

 knees ar parle; the four anterior tibiae and tarsi are pale reddish-testaeeous. The scape 

 beneath is pale reddish; the mandibles are red, black at the tip. E. guatemalensis is sepa- 

 rated from the other species of this group from our region by the thorax not being rugo- 

 sely punetured.« Cam.

Bezüglich der Grössenangabe des Thieres dürfte wohl ein Irrthum unterlaufen 

 sein; es sollte etwa 3 — 4 oder 6—7 Mm. heissen, anstatt 3 — 7 Mm., denn ein Längen- 

 unterschied um das Doppelte oder gar mehr ist bei Evania innerhalb einer und derselben 

 Art kaum denkbar.
