Professor Piper stated that Dr. Fletcher reported the larvae of 

 Therina somnlaria as completely defoliating the oak trees in 

 portions of Vancouver Island several years ago.* 



NOTE ON THE LARVA OF MELANCHROIA GEOMETROIDES 



WALKER. 



By HARRISON G. DYAR. 



Mr. Schwarz brought home from Cuba some larvae of this 

 species in alcohol, and three moths that he had bred. He found 

 them toward the end of December on a cultivated plant, Otaheite 

 gooseberry ( Cicca disticha), at Cayamas, Cuba. They had de 

 foliated the plant and ate large patches of the bark besides. Mr. 

 Schwarz fed the larvae that he bred on the bark as there were no 

 more leaves left. The three moths lack entirely the usual white 

 dashes on the upper sides of the wings, though one shows a trace 

 of them below. Gundlach, in Ent. Cubana, records an experi 

 ence similar to that of Mr. Schwarz of the larvae eating the bark. 



I^at'va. Head rounded, full, narrowed a little above, slightly bilobed, 

 broad; bright red, labrum pale yellow, jaws and ocelli black. Body uni 

 form, not elongate, equal, central segments about as long as wide, abdom 

 inal feet on joints 10 and 13, the anal pair with triangular plates; all 

 feet bright red. Body black, marked with pale yellow; four to six trans 

 verse dorsal bars on each segment, the central ones longest, the marginal 

 ones shorter and rounded, separated by a subdorsal area of ground color 

 from a similar lateral series, the base of which are more confused and 

 partly confluent. An even, broad, ventral stripe of pale yellow, somewhat 

 transversely barred on the annulets like the dorsal markings. Tubercles 

 obscure, concolorous, seta; moderate, black. 



NOTE ON THE GENUS LEUCOPHOBETRON DYAR. 

 By HARRISON G. DYAR. 



I proposed this generic term in 1897 for the Cochlidian species 

 argentijlua Geyer and argyrorrhea Hiibner, but gave no exact 

 characters. I have now before me two male specimens of argen- 

 tiflua from Cayamas (E. A. Schwarz), and Santiago, Cuba 

 (Capt. Wirt Robinson), and give from them the generic charac 

 ters. In Ent. Cubana, p. 274, Gundlach refers to this species
