in Hym. Conn., p. 328, it probably was not this species for he 

 says "exserted portion of ovipositor about as long as the abdo- 

 men." 



26. Cryptus (Spilocryptus) nuncius Say. 



Cry plus nuncius Say, Boston Journ. Nat. Hist., vol. 1, 1835, p. 237 (Leconte 

 ed., vol. 2, p. 693); Riley, Amer. Ent., vol. 2, 1870, p. 100. (Synonymizes 

 extrematis Cresson with nuncius); Riley, 4th Ann. Rept. Ins. Mo., 1871, 

 p. 110-111. (Recognizes extrematis Cresson and nuncius as distinct). 



None of the species listed in the synonymy with nuncius by 

 Dalla Torre is correctly so placed. With the possible exception 

 of sordidus Provancher, which its author says has the second 

 tergite medially aciculate, all of these specimens are apparently 

 synonyms of extrematis Cresson. Provancher's extrematis is not 

 the same as extrematis Cresson, for the face, clypeus, mandibles, 

 and tegulae are said to be white, while the true extrematis has all 

 of these parts black. 



27. (Cryptus) Crypturopsis orbus (Say). 



Cryptus orbus Say, Boston Journ. Nat. Hist., vol. 1, 1835, p. 231 (Leconte ed., 



vol. 2, p. 688). 



Hemiteles orbus Walsh, Can. Ent., vol. 2, 1869, p. 9-10. 

 Mesostenus diligens Cresson, Can. Ent., vol. 10, 1878, p. 207. 

 Lymeon annulicornis Ashmead, Ins. Life, vol. 7, 1894, p. 243. 

 Crypturopsis annulicornis Cushman, Proc. U. S. Nat. Mus., vol. 55, 1919, p. 521. 



(Possibly synonymous with diligens.} 



The male of diligens agrees in every way with Says' descrip- 

 tion. Examination of more specimens since the publication of 

 Cushman's paper convinces us of the identity of diligens and 

 annulicornis.

 Maryland, from a spider egg-cocoon.

29. (Cryptus) Stylocryptus subclavatus Say. 



Cryptus subclavatus Say, Boston Journ. Nat. Hist., vol. 1, 1835, p. 237 (Leconte 



ed., vol. 2, p. 693). 

 Phygadeuon rotundiceps Provancher, Nat. Can., vol. 9, 1877, p. 12. 



A homotype (Rohwer) of rotundic-eps agrees in every way with 

 the description of subchatus except that the abdomen is not 

 blackish at the apex, but this is variable, some specimens show- 

 ing a distinct infuscation. The bifoveate prescutellar groove 

 with its distinct margin, the stout, subclavate antennae, 

 depressed thorax, and nearly parallel intercubiti are character- 

 istic and are exactly as described for rotundiceps. The species
