dilutiorihus ; alis metatJiorace longiorihus^ fusco-hi/alinis, stigmate et

 ohsoleta ; pedihus testaceis ; terebra segmenti 1"°' longitudine. 



$ Long. 1 lin. (terebra excl.) 



Head very large, twice as broad as the thorax, and with the thorax 

 and 1st segment of the abdomen finely punctulate. Antennae tri- 

 colorous, joints 1 — 3 — 4 testaceous, the rest blackish, 7 — 8 white above. 

 Areolae of the metathorax distinct ; areola superomedia short, small ; 

 posteromedia hexagonal, narrow above, widest in the middle, and slightly 

 decreasing in width thence to the apex ; areolce spiraculiferce bisected 

 by a transverse carina; all the areolae distinctly punctulate. First 

 segment of the abdomen with the tubercles inconspicuous, medial; 

 three times wider at the apex than the width of the petiole, punctulate, 

 with 2 abbreviated longitudinal carinae, and 2 lateral longitudinal fur- 

 rows; apex glabrous. Segments 2, etc., hardly punctulate, shining, 

 black, sometimes more or less pitchy. Terebra fulvous, the sheaths 

 testaceous, tipped with black. Fore-wings with a triangular stigma ; 

 the apical nervures imperfect (in one specimen the radial cell is closed 

 on the right ride, and open on the left) ; areolet transverse, 4 angular 

 or irregular, the lower nervure incomplete (in one individual the areolet 

 is obsolete, reduced to a puncfciform knot ; the same insect has also 

 rather shorter wings). 



I took four of this distinct and unnoticed species last month, in a 

 wood near Milford Haven.

A. nigra, antennis fuscis, basin versus testaceis ; pedibus, abdominis 

 segmento 1°** apice, 2'^° toto, testaceis ; segmentis 3*"° et sequentibus fus- 

 cescentibus ; alis angustis, metatJiorace longioribus,fusco-Jigalinis, stigmate 

 et radio pallide fuscis, areola irregulari, extus aperta ; terebra abdominis 

 longitudine. $ Long. \\ lin. (terebra excl.) 



Head broader than the thorax ; both finely punctulate, almost 

 coriaceous. Joints 1 — 5 of the antennae testaceous, the rest dusky, 

 darker at the apex. Areolae of the metathorax not so distinct as in the 

 preceding ; the superomedia irregularly hexagonal, slightly narrowed 

 above ; areola spiraculi/erce bisected as in the preceding ; all these 

 areolae shining, nearly impunctate. First segment of the abdomen 

 with the tubercles medial, inconspicuous ; only twice as broad at the 

 apex as at the base of the petiole ; sub-rugulosclg punctulate ; black, the 

 apex testaceous, glabrous ; 2 lateral carina? not reaching the apex.
