which 1 have placed among the A\i//(ixr////ir. or iVoz/aj^T/'iu/u' of Dr. Harris. 

 The group which 1 have called Sfir/i/i(V is in some measure intermediate 

 between the Calphue and P/i/sii)ue. The tact that the tibiae are often 

 armed with a claw (Stiria. Basi/oi/cs) may be taken as an approximation 

 to the /fc/iot/ii/ia', where the tibiae are usually armed and have the tibiae 

 spinose. 



The typical genus of the Flusiime, F/usia, has a wide distribution and 

 is numerous in species. The type is the European P. c/irys/tis, and we 

 owe the generic name to Fabricius. 1 would refer the student to my Cata- 

 logue of May., 1874, where 1 have been at pains to give the date and the types 

 of the genera then described. This labor will, I think, be fotmd to have been 

 well expended, and to afford a good and reliable basis for the generic 

 synonymy. However we may extend or alter the contents of the genera, 

 it is well to keep the real meaning of the generic names before us by a 

 reference to the type. We can thus judge how far we are willing to 

 dei)art from the typical structure for the purpose of getting good working 

 genera. I add here the generic types since 1874 and arrange the genera 

 as follows. I do not think the labial palpi of Plusiodonta are really inter- 

 mediate in form between Calpe and Plusia, but it is not unreasonable to 

 follow witli that genus. 



The two groups or sub-gruups differ as follows : Front often prominent, 

 rough, with a roughened projection, sometimes circular, cup-like, or hardly 

 depressed, or with a central elevation ; again with a superior ridge or a 

 tubercle ; labial palpi weak, with the terminal joint conical or concealed ; 

 abdomen smooth, untufted, often with exserted ovipositor. The infra- 

 clypeal plate is pronounced. Stiriince. 



Front smooth, tibiae unarmed ; palpi moderately long, with pointed 

 third joint: vestiture more hairy: l)od\ often tufted on dorsal line.

 Basilodes Guen. (1852). 



Type: iJasilodes Pepita Guen. 



Eyes naked, unlashed. Thorax quadrate ; patagia detlected at tips. 

 \'estiture consisting of hair-like scales, mixed with broader scales and with 

 short, broad, underlying scales on thorax. Fore tibiae not truncated, with 

 a single terminal claw ; middle and hind tibiae unarmed. Body untufted; 

 $ abdomen terminating in a somewhat sudden slope to the extruded ovi- 

 ]»nsitor. Pnl]ii hairv. projecting beyond tlie front, with conical third joint.
