Habitus et statura insecti superi^s descripti sub nomine D. tenuipedis, tainen 

 pauUo minor coloribusque obscuris diversa. Caput nigrum, facie os ver- 

 sus acuminata, et subtus utrinque in spinam piceam terminata. Pedun-

 giores, graciies, fulvo-picei, apice nigri, in medio spina perbrevi arinati, 

 alteraque apicali. 0cm// ferruginei. Antenna; pallidee. Thorax totus niger,

 Pedes lutei, tibiis tarsisque anticis apiceque tibiarum posticarum obscurfe

 videntur, etsi subtils serie duplici tuberculorum spiniferorum parvorum 

 nigrorum instructa ; femora 4 postica apice spina brevi armata. Jlce disco 

 latfe infuscato apiceque macula magna terminal! nigrS,. 



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 

 l)eing regarded as a distinct species.
