 gen. nov., sp. nov., Oestride parasite de Bvhalis licJitensteini au 

 Katanga. [Gedoelstia cristata, an Oestrid parasite of Bvhalis 

 licJitensteini in Katano-a.] — l^evne Zool. Africaine, ii, pt. 2, 

 15th Feb. 1918, pp. 171-186. 



Gedoelstia cristata, of wticli larvae, pnpae and three adults 

 were obtained, is a new species parasitic on Lichtenstein's Haarte- 

 beest. This antelope is very common in Katanga and in almost 

 all of those that Avere examined nnmerons Oestrid larvae were 

 fonnd lodged in the long cavities of tlie frontal sinuses. 



The majority of the larvae belong to tlie species here described, 

 but along with them were fonnd two examples of another species, 

 as, yet unnamed. Four species of Oestrids are now known from 

 Bvhalis lichtenstcini. 



EiciTARDSON, Junr. (C. H.). An undescribed Hymenopterous 

 Parasite of the House-FIy. — Fsjjche, xx, no. 1, Feb. 1913, 

 pp. 38-89, 1 plate. 



In the summer of 1912, a number of specimens of an apparently 

 undescribed Pteromalid belonging to the genus Spalaurj,ia- were 

 reared from the pupae of Mnsca dnmestica. Sj)alanr/ia. mnsci- 

 darum closely resembles S. rufjosicnllis, Ashm., and specimens 

 reared from Stomoxys calcitrans in Texas agree in detail with 

 those reared from Musca domestica. 



This ecto-parasite, though commonly found in the puparia of 

 house-flies, was not known with certainty as a parasite of other 

 species. The Texas specimens, however, were obtained from a 

 region where S. calcitrans and M. domestica were breeding in 

 close proximity to one another and as their puparia are very 

 similar it is reasonable to suppose that the parasites did not 

 discriminate between the two. 



Brixton (W. E.). Mosquito Control Work in Connecticut in 1912. 

 —Jl. Econ. Entom., vi, no. 1, Feb. 1913, pp. 89-93. 



During 1912 considerable work was done in trying to control 

 the mosquitos along the shore region of Connecticut. A begin- 

 ning was also made in draining the marsh areas. Draining and 

 oiling was tried round New Haven, beginning with the most 

 important breeding i)laces. Oiling was practised on many fresh- 

 water pools and also on the salt marsh, and results showed that 

 even salt marsh mosquitos could be controlled by oiling, although 

 during July, August and September, when breeding is at its 

 height and the grass is tall and flooded at the roots, it is well nigh 

 impossible to cover the water with oil. It should only be applied 

 on the subsidence of the high tides, and then not until it appears 

 that the adult may emerge before the pools become dry. Drains 

 will last for many years if given slight attention each season 

 and if kept from being clogged by floating debris,
