Dec, igoi.] Packard : A New Genus of Moths. 191 



A SELF-DECORATING GEOMETRID LARVA. 



By Louis H. Joutel. 



While collecting beetles near Jamaica, N. Y., I noticed a little 

 mass of sand and dirt moving about. Not knowing what it could be 

 I picked it up, and in cleaning it I found a small Geometrid larva ; 

 not suspecting that the larva had decorated itself, but that it had been 

 emeshed by a spider, I put the larva in a paper box, and was sur- 

 prised on opening the same at night to find that it had bitten off 

 small pieces of paper and fastened them to its body in place of the 

 sand I had taken off. I then took off most of the paper shreds and 

 placed it in a tin with leaves and the next morning it had a fine coat of 

 green shreds on its back. Since then it has always added to its orna- 

 ments as they were brushed off or lost. This habit is evidently a 

 means of protection and an excellent one at that, as no one would ever 

 suppose that the small mass of refuse contained a caterpillar. 



A NEW GENUS OF SPHINGICAMPID MOTHS 

 ALLIED TO BUNiEA. 



By a. S. Packard. 



This genus is proposed for Buncea pJuedusa (Drury) and may be 

 named Lobobiinma in allusion to the slight lobe on the inner angle of 

 the hind wings. This well known species inhabits western and central 

 Africa. What other species of Buncea should be associated with it 

 could not be stated until their venation has been examined. Un- 

 fortunately I have only a male for examination, but the female is 

 represented as very similar in form and markings. I regard Buncea 

 alcynoe (Stoll) {^B. caffra Huebner) as the type of Buncea. 



Head wider than in Buncea. Antennse not so wide as in Buiuni, and the end 

 is subfiliform, with very short pectinations for a distance nearly equal to width of the 

 entire antenna; joints short and thick, two pairs of pectinations to a joint and those 

 of the distal pair are as long as the basal ones. Palpi larger and longer than in 

 Buvcta and the third joint reaches to the front, passing slightly beyond it. Thorax 

 with a definite collar, the prothoracic squamation being more distinct than usual. 

 Forelegs long and stout, tibia of $ with a naked, probably odoriferous, sack, like tha 

 present in certain Deltoid moths, on the under side two-thirds as long as the tibia 

 itself, and the scales separate from it, leaving it naked and easily seen from beneath.
