are larger, less numerous and less clearly defined. Upon re-examining the descriptions 

 of Fabricius, Gyllenhal, &c, I now believe that we must apply the name nigricornis to 

 this insect, and retain that of impressus for the Marshamian species, with the tibiae 

 more or less dusky. The species would then stand thus : — 



1. Haplocnemus nigricornis.

 lato, crebre punctato, lateribus dilatato-rotundatis, dorso convexo, medio obsolete

 punctatis, interstitiis laevibus. Lung. § — 1 liu. ; lat. f— i lin.' 



" The above description, from Manuerheim, agrees perfectlywell with the insect now 

 exhibited, and which I long since separated in my English collection as a distinct 

 species, but was unable to name. Finding some German specimens like it in the 

 British Museum collection, and bearing the name * rugosus,' I was led to examine 

 the descriptions of that species, which I must formerly have overlooked. I suspect 

 that the very inappropriate specific name applied to it was the cause of the oversight, 

 it being distinguished by the smoothness of its elytra. I have seen specimens of 

 this species in the Rev. A. Matthews' collection. It is usually smaller than 

 L. minutus and of a shorter form, and approaches more nearly to my L. testaceus, 

 but that insect is still shorter and broader, and has the elytra more distinctly punctate- 

 striated. Its colour appears to be always testaceous, whereas L. rugosus is black." 



Mr. M'Lachlan exhibited a Dipterous parasite on the larva of a Trichopterous 

 insect. It had been bred by Mr. Parfitt, of Exeter, from a larva-case of Limnephilus 

 marmoiatus, and had emerged through the water, though the eggs had probably been 

 laid by the parent fly when the case was floating on the surface. The name of Hydro- 

 tachiua Limnephili was proposed for this novelty. 



Papers read. 

 Major Parry communicated two papers : one entitled " Some Remarks on the 

 Catalogue of Lucanidae recently published by M. James Thomson in the 'Annales de 

 la Societe Entomologique de France';" the other entitled " Further Descriptions and 

 Characters of undescribed Lucanoid Coleoptera.'' The latter paper was supplementary 

 to that read by Major Parry at the October Meeting of the Society. The whole of 

 these descriptions are intended to be incorporated with others in a general Catalogue 

 of the family, to be published, with figures, in the ' Transactions ' of the Society. —
