JOURNAL OF PROCEEDINGS. Ill 



the larvae and perfect insects of a species of Diptera, which might 

 probably have been parasitic upon the Sli/lops. 



In support of this compound parasitism, the Rev. F. W. Hope 

 stated the circumstances he had observed relative to Ripiphonis 

 paradoxus, the parasite of the common wasp, which is itself para- 

 sitically attacked by a species o^ Anomalon, which last is the prey 

 of one of the minute Chalcididce. 



Mr. Westwood suggested, that as the Dipterous insects found 

 in the abdomen of the wasp by Mr. Shuckard were evidently spe- 

 cimens of a Trineura, Meig., in an imperfect state, the supposed 

 larvae being, in fact, their puparia; these insects, instead of being 

 parasitic on the Sti/lops, must have attacked the wasp after 

 death, it being the habit of some of the Trineurce to reside in ill- 

 preserved collections of natural history, &c. 



Mr. Stephens considered it probable that the eggs of the Tri- 

 neurce were deposited during the process of drying the wasp, as 

 he had noticed a British species of Lihellula to be attacked by the 

 Trineurce in a similar manner. 



The Rev. F. AV. Hope communicated a notice of a case from 

 the " Stamford Mercury," in which an old and infirm person had 

 been operated upon for an abscess in the mouth, on opening 

 which a brood of the " common house-clock" were dislodged. 

 The term black-clock being applied in Yorkshire to the larger 

 black species of Carahidce, it was suggested that the insects in 

 question might have belonged to a species of that group, as the 

 Sphodi'us leucoptlialus had been found under nearly similar cir- 

 cumstances. The common cock-roach and the Blaps mortisaga 

 were also suggested as possibly being the insects intended. 



The commencement of a memoir, entitled Dyt'iscidce Darrvin- 

 iance, by C. C. Babington, Esq., F. L. S., was read.
