British Braconidce. 79 



posterior impression. Segment 1 as in the preceding species, but 

 black at the base, and with less prominent tubercles ; longitudi- 

 nally striolated. Valves of the terebra filiform, black, paler at 

 the base. 



This species is distinguished with difficulty from 

 the ? of ccthiops, and perhaps only by the labial palpi, 

 which have been observed under the microscope by 

 Haliday and Eeinhard. My specimens are old and 

 useless, and have not been employed in this description. 

 Fresh examples are required for determination, and a 

 note of the palpi should be taken while they are pliant ; 

 otherwise the destruction of the insects may be necessary 

 in order to verify them. It may be noticed, however, 

 that in secalis the metathorax is somewhat shining, with 

 scattered punctures, and the squamulfe dull stramineous; 

 while in athiops the metathorax is rugoso-reticulate, and 

 the squamula3 fuscous. Euthe supposed his M. spurius 

 to be a variety of cethiops, but Eeinhard has determined 

 its identity with secalis. Haliday believed the Ichneumon 

 secalis, L., to be the present insect. In the Linnean 

 collection is a 2 ticketed "secalis, agricolator" ; and 

 another in bad condition, placed apart, and unlabelled. 

 Fitch has visited these specimens, which have a large 

 yellow head and long terebra ; the wings are not easily 

 seen, but the insects are undoubtedly Cenoccelius rubri- 

 ceps, Eatz. P. secalis is the species described by Eatze- 

 burg (I. c.) as sent to him by Hartig, and conjectured 

 erroneously to.be a parasite of Lasiocampa pini, L.

Labial palpi 2-jointed. $ black; antennae at the base, mouth, 

 and clypeus, dull testaceous; orbits broadly rufous; legs rufo- 

 testaceous, hind coxse fuscous above. ? black; antennae at the 

 base, head, and legs, rufo-testaceous ; abdomen piceous, its apex 

 obscurely rufous. "Wings narrower than in secalis, subhyaline, 

 nervures and stigma fusco-testaceous, squamulae dull yellowish ; 

 stigma broadly ovate, lanceolate ; radial areolet semicordate, 

 ending somewhat nearer to the stigma than to the tip of the wing.
