ALLOTRIA RUFICEPS. 241 



3. ALLOTRIA BUFICOLLIS. 

 PI. XV, fig. 10. 



Allotria ruficollis, Cam., Trans. Ent. Soc., 1883, 365. 



Black ; antennas and legs yellow ; head, prothorax, breast, meso- 

 pleurae at base and apex, metapleurse and base of abdomen, red ; tegulse 

 piceous; wings hyaline, nervures dull yellowish; radial cellule one- 

 half longer than broad. Antennae longer than the body, the third 

 joint straight and a little longer than the fourth, the last a little longer 

 than the preceding ; the apical joints are somewhat fuscous. Base of 

 abdomen pilose. 



Length 1| mm. 



Closely allied to A. pleumlis, but that has not the 

 mesopleurse black, the antennas are only yellow at the 

 base, the radial cellule is not much longer than broad, 

 and it is also a smaller species. 



Rare. Mull, in June. 



4. ALLOTRIA RUFICEPS. 

 PL XV, fig. 9. 



Allotria ruficeps, Cam., Trans. Ent. Soc., 1883, p. 365. 



Black ; pronotum, mesopleurse on lower side, and breast, piceous-red ; 

 legs reddish-yellow; joints one to four of antennae yellow, the rest 

 piceous ; head and petiole red. Wings hyaline, nervures fuscous ; 

 radial cellule not much longer than broad ; the cubitus is traced for 

 two-thirds of the wing. Antennae longer than the body ; the third 

 joint straight, distinctly one-fourth longer than the following; the 

 last is not much longer than the preceding. The pubescence on median 

 segment and base of abdomen is dense. ? . 



Length 1 mm. 



The radial cellule is shorter than in A. flavicornis, 

 and the shortness of it easily distinguishes it from A. 

 ruficollis, with which it has some resemblance in colora- 

 tion. It is longer than A. pleuralis, the antennae are 

 somewhat longer, and have the third joint longer in 

 proportion to the fourth, and the cubital nervure is 

 indicated, which is not the case in pleuralis. 



New Galloway, in June. Rare.
