 panying letter-press. 



In the hope that it may be of service to those who have not 

 sufficiently mastered the terminology of the veins in Diptera the 

 present figure is offered, with the correct names of the veins 

 appended. 



Colonel A. Alcock has recently published a paper on the 

 classification of the Culicidae/ in which he deplores the undue 

 rank apportioned to mere groups of species in this family, and 

 recognizes Corethrinae as certainly' belonging here, but follows

2 All three sets of terms have been used by good dipterologists but anterior 

 and posterior are eminently the best fitted for permanent adoption since these 

 relative positions ar'- constant in all wings in which both cross-veins are present, 

 whereas the other terms are sometimes inappropriate.
