The insects of this and the three following groups have the labial palpi very long and porrected obliquely ; 

 the antennse of the males bipectinated ; the wings when at rest forming a triangle ; the fore feet in the males 

 with singular brushes of hair ; the caterpillars with six or eight ventral feet. In the present group the wings 

 are abbreviated, nearly of uniform colour, without transverse markings, and the males are destitute of anterior 

 tarsi. It frequents fens. 



Species 1. — Mackochila cribralis *' — (Plate LXXIV., Fig. 16) — Measures 13 or 14 lines in expanse ; 

 wings whitish-ochre, paler on the disc, a small dot in the centre, and one or two oblique lines of dots beyond it 

 of black ; more or less obsolete ; bind wings paler, with a submarginal row of similar dots. Taken in the fens 

 of Huntingdonshire about the end of July.

PECHIPOGON, Hubner; Stephens. PYRALIS, pars, Curtis. 

 The palpi are porrected horizontally, and very long, with the terminal joint recurved ; the antennae bipecti- 

 nated nearly to the tip ; the fore wings elongate triangular, with oblique streaks ; the fore feet of the males with 

 fans ; the tarsi slender ; the larvae have only three pairs of ventral legs. It frequents woods. 



Species 1. — Pechipogon barbalis''' — (Plate LXXIV., Figs. 17, 18) — Measures from 11 to 15 lines in 



expanse ; fore wings ashy-brown, with three equidistant dusky strigse, the first incurved before, and the second 



very much bent a little beyond the middle ; the third nearly straight and subapical ; hind wings similarly 



strigose. The caterpillar is robust, and of a red-brown colour, with darker longitudinal lines ; it feeds on the oak 



and birch ; and the moth appears throughout the summer, in woods, and is a common insect. I have a very pale 



specimen with all the markings nearly obsolete.

PARACOLAX, HuBNER, Stephens. PYRALIS, pars, Curtis. 

 This genus diflfers from the two preceding, in having the long middle joint of the palpi curved and ascending, 

 and the terminal joint recurved ; the antennae slightly bipectinated in the males ; the head tufted ; the fore 

 wings slightly elongated ; the disc with dark streaks ; the anterior tibiae in the males mostly furnished with 

 brushes of hairs and incrassated, varying in the difi'erent species, and the fore tarsi occasionally wanting. 



Species 1. — Paracolax derivalis'^ — (Plate LXXIV., Fig. 19) — Measures 14 or 15 lines in expanse; 

 wings fulvous-buff, all with a dark central dot ; anterior with two dark incurved, and hind ones with a single
