154 Kev. T, A. MarshaH's monograph of 



not scutated. Radius of the fore wings subobsolete, isolated, 

 springing from a point remote from the 1st intercubital ; two cubital 

 areolets, the 2d imperfectly defined, all the exterior nervures being 

 obsolete. Terebra subexserted. 



The prolongation of the vertex makes the head appear, 

 from above, subhemispherical. The prae- and pobrachial 

 areolets are of equal length ; recurrent nervure sub- 

 interstitial ; stigma large and rounded, instead of tri- 

 angular. Metathorax bidenticulate. Tibiae subclavate, 

 rounded at the apex ; in the other genera they are 

 truncate. In addition to Haliday's species seven are 

 described by Forster, Verb. pr. Eheinl., 1851, pp. 30 — 38, 

 and one by Euthe, Berl. ent. Zeit., 1858, p. 4. Unlike 

 other Microf/asters, they run with great rapidity. In size 

 and colours they are variable ; in structure uniform.

(Fore legs, and sometimes the face, coxse, and

Black ; mandibles, palpi, fore tibiae at the base and aj^ex, 4 

 anterior tarsi, and apex of the trochanters, fusco-testaceous or 

 piceous. Wings whitish, with two more or less distinct dark 

 bands, separated by a whitish interval below the fuscous stigma ; 

 most of the nervures decolorous. Head and thorax minutely 

 punctulate, dull ; abdomen shining. Terebra subexserted. 3' ? •

Antennae ^ ? longer than the body, those of the J incrassated 

 in the middle, of the ^ longer, attenuated towards the apex. 

 Thorax minutely punctulate ; metathorax elongate, subrugulose, 

 bidenticulated, not much lower than the scutcllum. Legs stout, 

 4 posterior femora and hind tibiae incrassated, the latter clavate. 

 Calcaria shorter than i the metatarsus. The dark fascia) on the 

 wings are variable, and often obsolete. 



In a MS. note by Haliday, accompanying his types 

 preserved in the British Museum, A. germanus and suh- 

 fasciatus are united into one species. This is no doubt
