174 THE CANADIAN ENTOMOLOGIST. 



known, to the first monographer of Embia, the Veteran Entomologist — 

 Indefatigatus, Doctissimus ! 



The rudimentary venation separates this species from all known, by 

 the want of the lower branch of the sector. 



Prof Westwood in his monograph, 1. c, p. 374, mentions two appar- 

 ently distinct species in gum copal, probably from the eastern coast of 

 Africa, in the collection of Dr. Strong, of Brook Green — " one which, 

 from its size may probably be the Embia Savignyi ; seemed to possess 

 14-jointed antennae." The size oi E. Savignyi is so much larger that this 

 copal species can not be O. Westwoodi. 



The other species was of still larger size, with slightly stained wings 

 and 24 joints in the antennce. Both are unknown to me. 



The published copal insects contain no Embia. A careful examination 

 of the large collection of copal insects here did not give any more Embia.

Embia nigra Hagen, Synop. Psoc. et Embid., 1. c, p. 221-222 (no 

 description). 



Male, dry : Length of body 8 mill.; exp. of wings 13-15 mill. Head 

 dark fuscous, a little shining, sparingly covered with small pale hairs ; 

 head a little longer than broad ; the part behind the eyes narrower, 

 rounded, nearly orbicular ; above slightly convex ; eyes large, black ; 

 epistom quadrangular ; labrum large, fuscous in middle, rounded ; antennge 

 longer than head and prothorax, 13 joints present, fuscous, very hairy, 

 hairs long, brown; ist joint cylindrical, a little thicker than the others, 

 once longer than broad ; 2nd cylindrical, short, as long as broad ; 3rd as 

 long as ist, larger on tip; 4th to 6th short, very little longer than broad, 

 thicker on tip, 5th and 6th longer and thicker than 4th; 7th to 9th about 

 alike, similar to the preceding ones, but longer ; loth to 13th longer, about 

 four times longer than broad, more cylindrical ; rest wanting. Another 

 specimen has also 13 joints, but here the loth to 13th are not so elongated ; 

 perhaps the difference is caused by the preparation. Mandibles strong, 

 brown, with three black sharp teeth on tip ; the right majidible has the 

 inner teeth shorter ; max. palpi 5-jointed, the two apical ones longer, the 

 last one ovoid ; lab. palpi 3-jointed, fuscous, the apical longer, ovoid ; 

 labium pale, rounded, bifid ; head below brown, mentum blackish. Pro- 

 thorax brown, much narrower and shorter than the head, a little longer 

 than broad, and dilated to the wings ; sides oblique ; a transversal sulcus
