with the Pentarthrides in li.iviiig :i 5-jninted funiculus, but it was 

 placed by Wollaston ami)ngst the " sub-Hylastideou.s asperated types" 

 towards the end of the Cossonides, on I'ccount of its obvious affinity 

 with Hexarthrnm, Dendroctonomorplius^ and Calj/ciforus. The name 

 Wolladonia, Horn, has a few days priority over Tomolips, VVoll., but 

 as it is pre-occupied for a fossil genus of Palpicorn Coleoptera (fleer, 

 1852), it cannot be adopted. T. aspcratus, y^oW. ( ? ), it may be 

 stated, is almost certainly the sexual complement of T. hicalcaratus 

 ((J), similar differences occurring in a few cases amongst the Barids 

 (e. ff. in the genus Brachyharis, Faust). The two forms were received 

 in the same collection from Mexico, from the same collector, Truqui.

miltogram.ua OERMARI, Mg., 

 AND AMAUROSOMA FLAVIPES, Fln., FROM OXFORDSHIRE. 



BY J. R. MALLOCH. 



Some time ago I received from Mr. A. H. Hamm, of Oxford, a 

 number of specimens of Diptera for identification, amongst which 

 were several species which 1 cannot trace as having been recordeil as 

 British. I have already introduced two of these in the pages of this 

 Magazine, and now purpose adding two more. 



MiUocjramma cjermnri^ Mg., is, perhaps, the more interesting of 

 the two species, and if search is made near and about the burrows of 

 Hymen opt era, upon which these flies are parasitic, T have no doubt 

 that this and other members of the genus, as yet unrecorded as British, 

 may be met with. Mr. Hamm informs me that his specimens were 

 taken " on a sandy path in which were a number of burrows of 

 various Acideata,'' on August 7th, 1907. The locality given is " near 

 Shotover Hill, Oxford." 



In general appearance the species is not unlike M. punctnta, 

 Mg., but differs from that insect in having the base of the third 

 joint of the antennae and the two basal joints pale ; in having the 

 abdomen chequered, and without the three rows of spots present in 

 punctata ; and in the ^ by the absence of the long hairs on the fore 

 tarsi. It is not unlikely that this species may be placed in some col- 

 lections under punctata. 



AmaurosoiJia Jlavipes, Fin., is a much less conspicuous insect than 

 the foregoing, and belongs to another group, which, if worked pro-
