Species 10. Diopsis FUMIPENNIS, mihi. 
Tas. IX. Fig. 9. . 
D. capite thorace toto abdomineque posticé nigris, hoc antice saturate ferru- 
gineo, femoribus anticis gracilioribus, alis infumatis macula magna ter 
minali nigra. 
Long. corp. lin. 3. Expans. alar. lin. 53. 
Habitat in Senegallià? In Mus. nostr. 
Habitus et statura insecti superiüs descripti sub nomine D. £enuipedis, tamen 
paulló minor coloribusque obscuris diversa. Caput nigrum, facie os ver- 
sus acuminata, et subtüs utrinque in spinam piceam terminatá. Pedun- 
culi oculiferi cum oculis quàm thorace cum capite feré e tertià parte lon- 
giores, graciles, fulvo-picei, apice nigri, in medio spina perbrevi armati, 
alteraque apicali. Oculi ferruginei. Antenne pallidae. Thorax totus niger, 
nitidus, vix sericeus, et inter basin alarum et halteres spina brevi pallida 
utrinque armatus. Spine scutellares in specimine nostro unico deterun- 
tur. Abdomen elongato-subclavatum, saturat? ferrugineum, apice obscure 
fusco-nigrum (in coloribus abdomen Cheilosie Brassicarum simulans). 
Pedes lutei, tibiis tarsisque anticis apiceque tibiarum posticarum obscure 
fuscis; femora antica tantim paulló crassiora quàm postica et vix raptoria 
videntur, etsi subtis serie duplici tuberculorum spiniferorum parvorum 
nigrorum instructa ; femora 4 postica apice spina brevi armata. Ale disco 
latè infuscato apiceque macula magna terminali nigra. 
I at first hesitated whether this insect, which I purchased in Paris, was more 
than a variety of the D. apicalis; but the investigation of the characters of 
other species has induced me to consider its black head, dark terminal seg- 
ments of the abdomen, and clouded wings, together with some other circum- 
stances connected with its structure, noticed above, as sufficient to warrant its 
being regarded as a distinct species.
