psYcnoDA. 255 



dibles obsolete. Labnim and maxillcB as long as the labium ; maxiliiv 

 lancet-like. Palpi t'onr-jointed, cxserted, pubcseent, curved downward ; 

 joints of equal length. Antemi;« with from twelve to sixteen joints, 

 porrect, moniliform, vertieillate-pilose, a little longer than the thorax ; 

 first and second joints stouter than the rest. Thorax nearly round. 

 Wings obovate, broad, deflexed, very hairy, without transverse vein- 

 lets ; mediastinal vein rudimentary ; subcostal a little more than half 

 the length of the wing ; radial proceeding from near the base of the 

 cubital, forked before one-third of its length ; cubital ending at the 

 tip of the wing ; subapical ending at a little behind the tip ; two ex- 

 terno-raedial veins formed by a fork of the prasbrachial ; anal, axillary, 

 and subaxillary veins complete ; humeral veiulet near the base. Areolets 

 thirteen, — the humeral, the subcostal, which is mostly united to the 

 mediastinal, two radial, the cubital, the prajbrachial, which is very 

 short, the pobrachial, the subapical, two externo-medial, the anal, the 

 axillary, and the subaxillary ; posterior margin not excavated, nor in- 

 dented towards the base. Halteres of moderate size. Abdomen cy- 

 lindrical, with eight segments. Legs short, unarmed, rather thick ; 

 tibiaj without apical spurs. 



The species of this genus resemble little moths; their wings 

 being generally thickly covered with hairs. Some are very abun- 

 dant during the winter months when the weather is mild. When 

 walking up glass they move alternately from right to left and 

 from left to right, so as to describe small zigzags. 



The larva of F.phalanoides and that of P. se.qmnctata inhabit 

 dry cow-dungj they are long, subfusiform, depressed, with a slender, 

 straight, cylindrical tail, which is longer than the preceding seg- 

 ment. The pupa has two short appendages, thickened at the tips 

 behind the head ; the abdomen is tapering.

Hoaiy. Antennie with black bands. JFinr/s xinspolled. Halteres 

 white. 



The most abundant species, occurring not only on walls and 

 windows, but on shrubs, etc., everywhere; probably breeds in all 

 sorts of vegetable decay. (E. S. I.)
