82 THE CANADIAN ENTOMOLOGIST 



Anoplius similaris, n. sp. 



9. Black throughout; wings uniformly black. Closely to A. illinoiensis. 

 The clypeus is broadly, evenly concave below, in illinoiensis it is truncate and 

 consequently longer. The face is a little broader at vertex than in illinoiensis; 

 antennae and ocelli about the same as in that species; the metanotum is a little 

 shorter, more deeply grooved, the posterior slope more flattened across, the 

 hairs shorter and much fewer than in A. illinoiensis. The abdomen similar 

 but the last segment has only a few fine hairs, not the stiff bristles of 

 A. illinoiensis. Legs slender, hardly as spiny as in illinoiensis, the inner spur 

 of hind tibia a little more than one-half of basitarsus; the front basitarsus has 

 no noticeable spines above, but two or three on the outer under side. Venation 

 similar to A. illinoiensis, but submarginal cells a little larger, and the second 

 recurrent vein not curved. 



Length 15 to 16 mm. 



From Ithaca, N.Y., 14, 25 July, (Bradley). 



Lophopompilus autilone, n. sp. 



cf . Related by the male genitalia to L. cethiops, differs in that there is a 

 median, hairy ridge the whole length of the genital plate (in cBthiops only at 

 base). The under side of the first joint of the antennae is hardly hairy; the 

 hairs on the metanotum are not nearly as long or as dense as in cethiops, and 

 the whole body is less hairy. The clypeal margin is slightly concave; the third 

 sut marginal cell is triangular, receiving the second recurrent vein near the 

 middle, the latter bent near the middle; hind margin of pronotum almost angular; 

 apical ventral segments with scattered hairs only. 



Length 14 mm. 



From La Belle, 8-10 May, Ft. Meyers, 7 May, Florida, and Billy Island, 

 Okefenokee Swamp, Ga., all taken by Prof. Bradley. 



Pompiloides canadensis, n. sp. 



, 9 . Similar to P. cylindriciis and P. insolens; differs from both by the 

 shape of the basal plate of male genitalia being triangularly emarginate, the 

 sides of the emargination divergent (instead of parallel) ; the last ventral seg- 

 ment is not so deeply emarginate behind as in P. cylindricus. Black through- 

 out, not as much silvery as in P. cylindricus, the silvery appearance noticeable 

 on face, thorax and coxae. Head with rather longer hair than P. cylindricus, 

 venter with few, but distinct hairs. Third submarginal cell usually short 

 petiolate, the second sub-quadrate. About the size of P. insolens. 



From Truro, Nova Scotia, 12 Aug., (Matheson); and Val Morin, 29-30 

 July, Canada (Ouellet). 



Sophropompilus quadrispinosus, n. sp. 



9 . Deep blue; wings blackish, nearly uniform, legs and antennae black; 

 clothed with short hairs. Clypeus truncate, third antennal joint hardly equal 

 first, faint line to anterior ocellus, hind ocelli nearer to each other than to the 

 eyes, vertex from in front slightly convex, pronotum arcuate behind ; metanotum 

 short, hairy, faint groove on the base; abdomen with short hairs above, longer 

 at tip and below; femora plainly hairy above, inner spur of hind tibiae two- 

 thirds of the basitarsus, front tarsus has four long spines in comb on the first 

 joint, these are almost flattened; wings and venation as in 5. hyacinthinus .
