340 On Ilymenoptera in the British Museum. 



" Campoplex" divisus, Cress. — The specimens recorded from Mexico 

 by Cameron (Biol. Centr.-Amer. 1886, p. 306) have circular 

 spiracles. 



Haristceus nigrifrons, Cam., described from Mendoza, appears to be 

 congeneric with the same author's Pimplomorpha. 



Casinaria crassiventris (Catn.)= Campoplex crassiventris, Cam. Ann. 

 S. Afric. Mus. v. 1906, p. 93 : a co-type $ in the British 

 Museum compared. 



Omorga longiceps, Cam., is a typical species of this genus, allied to 



0. microsticta, Grav. 



Omorga rivalis, Cress. Trans. Amer. Ent. Soc. iv. 1872, p. 173 ; 



not a Limnerium, s. s. 



Omorga poly nesialis, Cam. Trans. Ent. Soc. Lond. 1883, p. 191, $ 



(?et d). 



Omorga fugitivus (K&\.)= Campoplex fugitivus, Hal. Trans. Linn. 



Soc. Lond. xvii. pt. 3, 1836, p. 318. The d" type is very 



like Omorga ensator, Grav. 

 " Campoplex" meridionalis, Ashm. Journ. Linn. Soc, Zool. 1894, 



p. 139, J $ j fr° m St. Vincent. The tf type in the British 



Museum has circular spiracles, and appears to be a species 



of the genus Omorga, Thorns. 



Angitia maculipes (Cam. )= Enytus maculipes, Cam. Invert. Pacif. 



i. 1905, p. 132. A true 2 of Angitia, Thorns., with no 



areolet. 



Angitia blachburni, Cam. loc. cit. p. 192, $ (? et J). 



Angitia haivaiiensis, Cam. Manch. Mem. v. 1886, p. 271. 



Angi 4 ia annulipes (Cress, et Ashm.) = Limneria annulipes, from the 

 same source, certainly belongs to Angitia, Thorns. 



Nepiera africana (Cam.) = Linmena africana, Cam. Bee. Albany 

 Mus. i. 1904, p. 175, J • This I consider to belong to the 

 genus Nepiera, Thorns. ; two 2 2 i' 1 ^ e British Museum 

 are also labelled by Cameron " Diadegma fasciannulata, Cam. 

 Type. Pretoria," and " Limnerium stellaboscliense, Cam. 

 Cape Colony." 



" Tryphon" obstructor, Smith, Trans. Ent. Soc. Lond. 1878, p. 4, 



from New Zealand, is a Campoplegid, and, I think, a Melo- 



boris, Thorns. Both the type and variety with the hind coxse 



black above are <5 S and difficult to place with certainty. 



[Of the other two Tryphoninse mentioned, I. c. p. 3 : Scolobates 



varipes = Bassus Icetatorius (cf. Mori. Ichn. Brit. iv. 1911, p. 82), 



and S. intrudens = a, remarkable form of Campoplegid (cf. Bevis. 



Ichn. iii. 1914, p. 126), with circular metathoracic spiracles.] 



Limnerium fugitlvum (Say). — Specimens received through Biley 

 from the United States, labelled "fugitiva, Say," belong to 

 Limnerium, sensu Thorns.
