28 PROCEEDINGS OF THE NATIONAL MUSEUM vol.74 



hind trochanters black and white; hind tarsus, except base and 

 apex, white. 



The type of candidus is from New York and those of alhamacu- 

 latus from Michigan. The other two specimens in the National 

 collection are from Maiden, Mass., September 9, 1879; and Florida, 



Except for slight differences in size and in extent of white mark- 

 ings, all specimens are very much alike. 



CRYPTUROPSIS FORTIS (Cresson) 



Mesostenus fortis Cresson, Can. Ent., vol. 10, 1878, p. 206, female. Type. — 



No. 1177, Acad. Nat. Sci. Phila. 

 Mesostenidea fortis (Cresson) Viekeck, Hym. Conn., (1916) 1917, p. 329. 

 Crypturopsis fortis (Cresson) Cushman, Journ. Wash. Acad. Sci., vol. 15, 1925, 

 p. 390. 



As suggested by Cresson this may possibly be the female of can- 

 didkis, but the greater extent of white markings in the female is very 

 unusual. JMoreover, there is in the National Collection a male which 

 agrees in this respect with fortis and is apparently distinct from 

 candidus and which I take to be the male of fortis. 



This male differs from cmididus as follows: Face distinctly less 

 than half as long as broad, malar space much shorter than the basal 

 width of mandible ; diameter of ocelli fully three-fourths as long as 

 basal width of mandible; propleura apically white; mesosternum 

 and hind tarsus entirely white. 



The female type has the mososternal marking reduced to two large 

 spots so shaped that together they form a jew's-harp-shaped mark. 



The type from New York and the male described above, which 

 is from Highspire, Pa., July 30, 1910, W. S. Fisher, appear to be 

 the only known specimens of this species. 



CRYPTUROPSIS ABDOMINALIS, new species 



Fig. 3a 



Very distinct from all the other species in its largely red abdomen. 



Feincde. — Length, 12 mm. ; antennae, 9 mm. ; ovipositor, 3 mm. 



In stature and structure nearly identical with audax but malar 

 space fully as long as basal width of mandible and sculpture of head 

 and thorax somewhat coarser and denser, with scrobes arcuately 

 striate and metapleurum punctuate-ru,gose ; white markings as in 

 audax but somewhat less extensive on thorax; white orbits rarely 

 interrupted behind top of eyes; antennal annulus incomplete below; 

 scutellar carinae always white marked; coxae black and white, hind 

 coxa more or less red especially at apex on inner side; front and 

 middle trochanters white ; legs otherwise testaceous, the tarsi slightl}' 

 paler; abdomen ferruginous, base of first and apices of first and 

 second tergites indefinitely yellowish. 



Tijfe locality. — Put in Bay, Ohio.
