An insect much feared in Macedonia, where it bites man, usually at 



night and cliiefiy indoors, has been identified as the Bethylid, 



Sclerodermns sidncyaniis, Westw. It appears not to be a case of 



dehberate attack, the insects probably seeking shelter in the clothing 



and biting when disturbed by any movement. 



A note is also given on a Reduviid bug, Ploiaria domesiica, Scop., 

 found on walls and under mosquito nets. It apparently feeds on 

 engorged specimens of Phlcbotomus papatasii, Scop., and probably 

 also on bed-bugs.

 The information here given concerning Karyolysus has already 

 been noticed [R.A.E., B, viii, 208]. During these observations, which 

 were carried out in Spain, three parasites were found that could not 

 be placed in this genus owing to differences in their development, and a 

 new genus Schellackia was erected for their reception. Schellackia 

 ■ bolivar i was found in Acanlhodactylus vulgaris and Psanimodromus 

 hispanicus, and its development in these lizards is described. This 

 parasite is also carried by the Gamasid mite, Liponyssus saurarum, 

 Oudms., but the latter is only a mechanical carrier and not at all 

 essential to the development of the parasite. Infection has been 

 produced by feeding healthy lizards on the livers of infected animals.

 Melbourne, ii, no. 10, October 1920, pp. 607-609, 3 figs. 



An account is given of a parasite of Tabanids, blowflies and other 

 Diptera in Tasmania, wiiich attaches itself to the pseudo-tracheal tubes 

 of its host by strong, hooked jaws. It appears to be somewhat similar 

 to a hyper-parasite infesting larvae of Limnerium validum in the 

 caterpillars of Hyphaniria textor, which was found in America, and 

 proved to be a stage in the development of a Chalcid belonging to the 

 genus Perilampus. A somewhat similar stage in the life-history of 

 another Chalcid, Orasema viridis, had been named " planidium," to 

 indicate the motile and wandering habits that it possesses. 



The Tasmanian parasite has a general resemblance to the American 

 ones, but differs somewhat in anatomical details, and also in its habits.
