On the Subfamilies Antichlorinse and Charideinse of the Lepido- 

 pterous Families Zyg^enidse and Arctiidae. By Arthur G.

(PX.ATE XXIX.) 



Iisr a former communication to the Society I considered the ar- 

 rangement and structure of the subfamilies of typical Zygsenidge ; 

 I shall now proceed to investigate the aberrant subfamily A.nti- 

 ehlorinse and the Arctiidae of the group Charideinse, hitherto re- 

 ferred by entomological authors to the Zygsenidae. Both of these 

 subfamilies are characterized by having the usual number of 

 branches to the median nervure of secondaries ; bvit the Chari- 

 deiuae are of a more robust, and consequently less typically Zygae- 

 noid form ; the arrangement and branching of the wing-veins are 

 altogether more like the Arctiidae ; and, as a rule, the wiugs are 

 more densely clothed with scales. The larvae, so far as we know 

 them, are also very hairy, and ornamented with long diverging 

 tufts. Owing to loss of last page of MS., the Antichlorinae are 

 referred erroneously to the Arctiidae.

Grenus Mallosteihus, n. gen. 



Palpi rather long ; thorax broad, and fluffy in appearance ; abdo- 

 men gradually narrowing backwards to the anus, which has a 

 terminal tuft of short hairs: wdngs semiopaque ; lower radial 

 of primaries branching from the third median branch ; subcos- 

 tals of secondaries forming a simple fork from upper extremity 

 of discoidal cell ; median branches three in number, the first 

 emitted before the end of cell, the second and third forming a 

 fork from the lower extremity of the cell, the false radial and 

 its recurrent nervure running from the base of the median ner- 

 vure through the cell, along the edge of the third median branch 

 to outer margin. Type M. metamelas, Walker.
