MACROPHYA RIBJS. 133 



On the Continent it has only been recorded from 

 Scandinavia and Germany. 



Obs. Thomson quotes Macrophya crassula, Kl., as a synonym of albi- 

 puncta, but this is a mistake, Klug's species is larger ; the markings 

 are yellowish, the mark on the pleurae is larger, pronotum broadly 

 marked with yellowish-white, the hinder tibiae are not black at the base, 

 the stigma is not testaceous, the second recurrent is almost interstitial, 

 while it is received with albipuncta near the middle of the cellule. 



Thomson describes albipuncta as having the lanceolate cellule 

 uncontracted, but this is really a character of no value, since in 

 my specimens the form of this cellule is not quite the same in any of 

 them. 



Macrophya carinthiaca, KL, forms a section with only a single cellule 

 in the posterior wing.

Antenna? stout, a little longer than the head and thorax, not tapering 

 much towards the apex ; black, covered with a very short microscopic 

 down. Head black, densely covered with a longish grey pile, punctured, 

 clypeus deeply notched, almost to the base ; vertex raised ; the clypeus 

 at the base on each side, a spot on the labrum in front, mandibles at 

 the sides and palpi (faintly) white. Thorax covered with a longish 

 scattered grey pile. Mesonotum punctured, the lobes deep, especially 

 that in front of scutellum, which is raised and very deeply punctured ; 

 cenchri white ; pleura) semi- opaque, punctured. Abdomen longer than 

 the head and thorax. Legs black, a narrow spot on the side of each of 

 the four anterior coxae, a large pyriform one on the posterior, tro- 

 chanters, apical fourth of four anterior femora and tibiae entirely in 

 front (except at the extreme apex where the colour is black), and a ring 

 near the apex, tarsal joints more or less in the middle ; apex of posterior 

 coxae, trochanters, base and apex of femora, apical third of tibiae (except 

 at the extreme apex), and the apical joints of the tarsi more or less 

 white. The calcaria are black and reach near to the middle of the meta- 

 tarsus. Wings subhyaline, slightly brownish at the apex. 



The $ has the clypeus and labrum for the greater part white ; 

 anterior legs almost entirely white in front, as well as the posterior 

 coxse, trochanters, and base of femora. The apical part of abdomen is 

 marked with white below.
