BAKKS: NEW NEUROPTEROID INSECTS. 327 



European species. Last dorsal scfiment of male seen from above is rather 

 long, slightly narrowed and nearly truncate at tip, being only a little indented 

 in middle, from behind it is shallowly, broadly emarginate and shows below 

 a recurved spear-shaped plate \\ith a depressed middle area and appressed to 

 the ventral plate. 

 Expanse 18-26 mm. 



This has been considered the European S. fuliginom, l)ut tlie male 

 genitaha are of very different structure. 



SiALis ROTrxD.\, sp. nov. 



Type.— M. C. Z. 10,845. British Columbia: Bon Accord, 20 May 

 (J. Russell). 



Deep black throughout. The second of the connecting veinlets between 

 radius and radial sector is straight across, one vein between subcosta and radius, 

 about fourteen costal cross-veins. The last dorsal segment of the male shows 

 a large horseshoe-shaped depression; the ventral plate is large, extending 

 almost to tip of last segment, nearly truncate across tip; the lower appendages 

 of last segment are elongate, parallel-sided and from below the tip of last 

 dorsal segment appear as short, triangular pieces, separated by their width. 



Ex-panse c? 23 mm.; 9 33 mm. 



RAPHIDIDAE. 



Raphidia bifurca, sp. nov. 



Type.— M. C. Z. 10,846. British Columbia: Wellington (G. 

 Taylor). 



Black; face in front of antennae yellow; antennae yellow on basal part, 

 beyond brown; vertex with the usual red marks, the median one constricted 

 near middle, the lateral ones very irregular; pronotum more or less pale 

 lineate behind; legs yellow -brown, femora darker; tip of superior plate of 

 male yellow. Wings hyaline, venation pale brown, yellow near base, stigma 

 long, pale yellow, four cells behind it. In general very similar to 7?. adnixa 

 but differs in genitalia, the superior plate (seen from above) being furcate, and 

 (seen from the side) it is tapering; the two lower processes are dark, rather 

 stout, and with a tooth or enlargement near inner base. In the female the 

 last ventral segment has a large, apical yellow spot, and a median ridge; the 

 ovipositor reaches to tip of wings. 



Expanse 27 mm.
