248 ALLOTRIA MICROCERA. 



any other British species of this group, and forms 

 almost a semicircle. 

 Rare. Mull, in June. 



(b) Abdomen at apex rounded ; the segments connate. 



16. ALLOTRIA MICROOERA. 

 PI. XIV, fig. 5. 



Charips microcera (Haliday), Marshall, E. M. M., vi, 181; 

 Cam., Trans. Ent. Soc., 1879, 117. 



Black, shining ; antennae pale testaceous, the basal joint black, the 

 apical joints pale fuscous ; legs pale testaceous, the coxse, femora, and 

 tibiae in the middle obscure fuscous ; base of abdomen with a dark fus- 

 cous hair-fringe. Antennas as long as the body, stout, the third joint 

 curved, thickened, longer than the fourth. Radial cellule small, 

 longer than broad ; the nervures curved, very faint. Abdomen com- 

 pressed, especially at the apical half. 



Length a little over 1 mm. 



A distinct species. The abdomen is differently 

 formed from what it is in the other species. It is longer, 

 more compressed, and instead of being oblique at apex 

 (looking at it laterally) it is semicircular. I can dis- 

 cover no trace of segmentation in the abdomen, and it 

 looks to me as if the second segment formed the 

 entire abdomen. The form of the antennas, wings, 

 and thorax agrees with Allotria, and in the absence of 

 a ? I now prefer to place it here rather than (as I 

 formerly did) in the Figitina. 



There is a specimen in Mr. Marshall's collection 

 labelled " Charips microcera" Mr. Marshall states 

 that " Charips microcera " was an insect so named in 

 MS. by Haliday, " allied to Allotria, but having the two 

 apical joints of the antennas connate" (Marshall, 1. c.). 



Col vend, Kircudbrightshire ; Dairy, Dumfries. One 

 specimen of what is no doubt the same species is 

 almost entirely piceous.
