PERICOMA. 257 



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

 brachial 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 autenniie 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 antcnnte 



after the second less distinctly knotted or petiolated, being rather 



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

Rather longer than P. pkalanoides. B//fo-fesfaceo//s, abdon/en and 

 Italleres hroicnish. Lerjs paler ; tarsi and tips of the tibiae brownish. 

 Antenna tcith the first two joints short, globose, each of the remainder 

 with a d//sk/j 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 obscurehj hyaline, tcith dark fringed veii/s and 

 margin, but witho/tt spots. 



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

 wood and at Blarney. (I.) 



2. soleata, n., Hal. MSS. Cei'vino-hirta, alarum ciliis fusco-vii- 

 cantib/is basi antice et apice pallidioribtis, tarsoru/n artic/dis exterioribtis 

 albo-viicantib/(s. 



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 faion-coloxired 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. AntennrB shorter than in the preceding sj)ecies. 



Bare. In Mr. Dale/s collection. (E.)

f/'ro-ndcantib/is annulatis, alls cinerco-hiriis, venis posterioribus alternis 

 nigro-ciliatis. 



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

 dorsum of the thorax, and base of the icings in front tcith faicn-coloured 

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

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

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

 slend/;r pl/imbeous-shbdng scales. Palpi moderately long ; second, tliird, 

 and fourth joints of nearly equal length. Antcumu (thirtecn-joiutcd ?) 

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