Squamule reddish. Abdomen testaceous with the Ist segment 
black. Similar to D. senilis (sp. 12), but the Ist segment is more 
slender, and its pubescence not so dense. ¢ Black, pubescent ; 
head large, wider than the thorax ; mandibles red, palpi paler. 
Antenne testaceous at the base. Thorax oblong; metathorax 
pubescent, slightly excavated behind. Wings hyaline, with an 
obscure tinge ; nervures and stigma fuscous, the former (according 
to Haliday) arranged as in D. senilis. Legs testaceous. Abdomen 
narrower than the thorax ; Ist segment slender, linear, punctate- 
rugulose, subcarinate ; tubercles obtuse, situated somewhat before 
the middle. @Q unknown; but compare D. gracilis (sp. 22). Length, 
13 lines. 
The single example, taken long ago by Walker, is too 
succinctly described by Haliday. He differentiates it from 
D. cincta (sp. 16) as being of a more elongate form, with a 
larger head, the 1st segment more slender, and the radial 
areolet smaller. 
Taken once in England.

Head subcubic, its length and breadth being about equal, not

peculiar to this species, is easy to recognise; the head also is as 
wide as the thorax, and less flattened than usual ; mandibles and
