PERICOMA. 257 



a a a. Forks nearly equidistant from the base of the wing; the prae- 

 hrachial areolet usually very short and indistinct ; the wing either 

 rounded at the tip or the point between the two intermediate simple 

 veins ; first joint of the antennae little longer than the others. 

 b. Wings rather pointed (lanceolate) (or ovate-lanceolate). Smaller 



species. Species 5-7. 

 b b. Wings rounded at the tips, ovate. (Joints of the antennae 



after the second less distinctly knotted or petiolated, being rather 



ovate; the whorls spreading.) Species 8-11. 



1. lucifuga, n., Hal. MSS. Testacea, parum hirta, antennis petio- 

 lato-globosis corporis longitudine, alls subhyalinis immaculatis, pedibus pal- 

 lidis, tarsis fuscis. 



Bather longer than P. phalcenoides. Rufo-testaceous, abdomen and 

 halteres brownish. Legs paler ; tarsi and tips of the tibiae brownish. 

 Antennae with the first two joints short, globose, each of the remainder 

 with a dusky globose base and a long pale petiole ; the whorls of hairs 

 long and somewhat incurved, but lax. Pubescence not abundant, so 

 that the wings appear obscurely hyaline, with dark fringed veins and 

 margin, but without spots. 



Inhabits shady moist spots in woods. In September, at Holy- 

 wood and at Blarney. (I.) 



2. soleata, n., Hal. MSS. Cervino-hirta, alarum ciliis fusco-mi- 

 cantibus basi antice et apice pallidioribus, tarsorum articulis exterioribus 

 albo-micantibus. 



Resembles P. calceata with respect to the four exterior joints of the 

 tarsi, which are glossed with yellowish-white, but the acute wings, etc., 

 do not agree with Zetterstedt's description of that species. It is pretty 

 thickly clothed with fawn-coloured hair, a couple of rather indistinct 

 fuscous tufts towards the fore edge of the wings, viz. at the fork of the 

 radial, and above the opposite fork of the externo-medial (second) ; the 

 long cilia shift in colour to dusky, except at the apex and the humeral 

 tuft at the base. Antenna shorter than in the preceding species. 



Rare. In Mr. Dale's collection. (E.) 



3. bullata, n., Hal. MSS. Cervino-hirta, abdomine palpis pedib us- 

 que plumbeo-micantibus, antennarum verticillis crateriformibus margariti- 



fero-micantibus annulatis, alls cinereo-hirtis, venis posterioribus alternis 

 nigro-ciliatis. 



Scarcely larger than P. phalcsnoides. Plumbeous. Vertex, front, 

 dorsum of the thorax, and base of the wings in front with fawn-coloured 

 hairs. Whorls of the hairs of the antennae very coarctate, hiding the 

 joints, curved inward, cup-shaped, like a bubble, and shifting with opa- 

 line tints like a soap-bubble. Palpi and legs thickly clothed with fine 

 slender plumbeous-shining scales. Palpi moderately long ; second, third, 

 and fourth joints of nearly equal length. Antennae (thirteen-jointed ?) 

 nearly as long as the wings. Wings with cinereous hairs ; radial vein
