species, three of which were unnoticed by systematic writers. 

 One of these latter, the (7. bellana, which was captured at Edin- 

 burgh by Mr. Curtis, has been selected to illustrate the genus^ 



The genera of Diptera figured, are eight in number, several of 

 them being new to the English reader, and most of the insects 

 being also unknown to our catalogues. The single Apterous 

 genus, Pulexy is illustrated by an hitherto undescribed species, 

 that of the Mole, which is the largest that has yet been observed. 

 The dissections which accompany this figure, are given with ex- 

 treme care and minuteness. They are taken from the P. irritans^ 

 in which, as in the greater number of the species, no antennas are 

 visible. In a subsequent number the position and structure of 

 these organs in the P. HirundiniSy are pointed out ; an important 

 addition to our knowledge of the jiptera^ among which it appears 

 not improbable that several groups may hereafter be satisfactorily 

 established. The two Omalopterous genera, Craterina and 

 Melophagus^ founded on the parasites of the Swallow and the 

 Sheep, have also received especial attention. In the remarks on. 

 the former, the general structure of the insects of this order is 

 explained, and the dissections of the trophi are more than usually 

 elaborate.
