THE FAUNA OF SCOTLAND. 87 



16. A. MACULICOLLIS, Sp. HOV. 



Black; head red ; antennae and legs yellow, the apex of antennae 

 inclining to fuscous ; a large obsciiro red mark on the sides of pro- 

 thorax ; wings hyaline ; nervures f ascous ; metathorax, scutellum, and 

 base of abdomen densely covered with longish white hair. Antennae 

 longer by about one-fourth than the body, attenuate, the last joint 

 compressed, longer than the penultimate ; fourth joint longer than 

 either the third or fifth. Radial cellule broad, short ; the apical 

 branch of the nervure curved, scarcely double the length of the 

 oblique basal portion, which is scarcely one-fourth longer than the 

 cubital branch, cubitus scarcely reaching to the middle. Besides the 

 reddish mark in the centre, the prothorax is reddish-piceous along the 

 edges, especially at the pronotum. Male. 



Length somewhat more than 1*5 mm. 



Nearly related to A. macrophadna, but easily known from it by the 

 much shorter radial cellule, by the reddish prothorax, and by the 

 entirely yellow antennae.

18. A. BASIMACULA, sp. nov. 



Black ; the head (the vertex obscured with black) and base of 

 abdomen red ; the five basal joints of antennae and legs yellow; wings 

 hyaline, the nervures testaceous; metathorax and base of abdomen 

 densely covered with long white hair. Antennae a little longer than 

 the body, stout ; the fourth joint longer than either the third or fifth ; 

 the last joint about one-fourth longer than the preceding. Areolet 

 elongated, of moderate length ; the basal branch of nervure scarcely 

 double the length of apical, and not much curved ; cubitus not traced. 

 Female. 



The male has the antennae longer, with the third joint slightly 

 curved; the femora are darker, the yellow being suffused with fuscous. 



Length scarcely 1 mm. 



The pleurae and mesonotum incline to piceous. Readily known 

 from the preceding by only the five basal joints of the antennae being 

 yellow, and by only the third joint being curved in the male.
