uiiddle of the costa is a very dark g-roy or ijlack ol)li{|iio streak, hut 

 there are no other (kjfiiiite uiarkiug-s ; cilia dark grey. Posterior wing-s 

 grey, with pale fuscous cilia. 



Hitherto scarce; but Mr. Weir has bred tlie species in July, 

 from larviu feeding in th(; shoots of (jcnisla ihicloria, \\\ June. 

 Mr. Weir found tliem at Pcmburv, near Tunbridge Wells.

 Head smooth. Ocelli none. Anteuntic setaceous, remotely dcutieu- 

 late (of the $ , viewed through a lens, ciliated). Tongue; of moderate 

 length, clothed with scales. Labial pal])i, with the second joint be- 

 neath, formed like a brush, with the hairs produced in front ; Uie lasL 

 joint sii/oolh, poi)ited, recurved. Wings elongate, 7cilf/, moderate cilia ; 

 the posterior trapeziform, very slightly retuse before the apex. In the 

 anterior wings the furcate apical vein runs into the costa liefore the 

 apex ; the secondary cell is not indicated ; the nx^dian vc;in terminates 

 in a fork; the subdorsal vein is furcate ; the submediaii is not thick- 

 ened. In the posterior wings the costal cell is without any peculiarity; 

 the subcostal vein is furcate from the transverse vein; the median vein 

 is trifid. 



Of five continental species, only two liave been observed in 

 this country. The iiabits of the perfect insect are very similar 

 to those of the preceding genus. The habit of the larva of J//. 

 jlLir^ine/fus is to feed near the ends of the junii)er twigs, in a con- 

 siderable mass of web, which at first sight appears extremely lik(! 

 the abode of a spider. Whether this haljit prevails, in all the 

 other species of the genus, 1 am not aware (Fischer's figure of the 

 larva of Jnmj'jerellKn shows a complete accordance with the habit 

 of the larva of Marfjinelli'-s).
