468 Messrs, E. e Elliott and Claude Morley on the 
or Dorchaschema nigrum, Say, which is very rare and 
occurs only in the Southern States. 
1084. OBEREA ERYTHROCEPHALA, Sch.* 
Morley (Ichn. Brit., iii. 254) is sceptical respecting 
Schmiedeknecht’s suggestion that the Pimplid, Procinetus 
decimator, Grav., which is usually found among HLuphorbia 
cyparissias, in whose stems this longicorn feeds, attacks 
Oberea, and regards it as more probably attached to the 
Lepidopterous Gortyna flavago in thistle stems. But 
Pastor Konow is stated by Marshall (Bracon. d’Europ., 
ili, 28) to have bred several individuals of both sexes 
of Vipio guttiventris, Thoms., from the larvae of this 
longicorn in Mecklenburg. 
1086. OBEREA TRIPUNCTATA.* 
A new species and genus, Zaleptopygus Obercac, have 
just been published by H. L. Viereck (Proc. U.S. Nat. 
Mus., 1911, p. 294) for the reception of an Ophionid ich- 
neumon, allied to Cremuastus, Grav., which has been bred at 
Chicago from this host by Girault. 
109. Zetropiwm luridwm, Linn. 
Xylonomus precatorius, Fab., is said to prey upon this 
species, as well as upon the above Callidw, by Dalla 
Torre (Cat. Hym., 11, 386), who refers to Ratzeburg as 
his authority. 
110. Tetropiwm castaneum, Linn. 
The Lissonota we previously referred to under this host 
is not L. palpalis, as tentatively suggested, but L. varicova, 
Thoms. (ef Morl., Ichn. Brit., 111., 220). 
110a. OEME GRACILIS, Lec.* 
From this American longicorn, Ashmead has described 
a new species of Ratzeburg’s genus Husandalum, called 
Ratzeburgia Coquilletti (Proc. Ent. Soc. Washington, 1896, 
p. La):
