332 THE CANADIAN ENTOMOLOGIST. 



the fourth and fifth and the distal half of the third joint pure white, mid 

 femora markedly swollen. Ungues missing on all but the hind legs, where 

 they are white, simple and very broad, rather leaf-like. 



Wings clear, almost white, partly denuded, but with broad scales, 

 some of them as symmetrical as in Maiisotiia^ others suggesting the "heart- 

 shaped " scales of ^/^r/^/^/f?;;/^^/^, mostly brown, but some white scales, 

 an irregular white spot just exterior to the root of the third long, vein, and 

 extending on the second long, and subcosta, but not on the costa, costal 

 scales as in Uranotcenia. The cells very short, first submarginal at least 

 one-third shorter than, and not so wide as the second posterior cell ; 

 supernumerary and mid cross-vein about the same length, meeting at an 

 angle, and the posterior cross-vein about one-half the length of, and three 

 times its length distant, anteriorly, from the mid. 



Length, 3.5-4 mm. Habitat: Reine Regente, Mindanao, P. I. 

 Taken Feb. 



The markings are distinctive, the triangular spots on the abdomen 

 being very noticeable. _ 



It seems probable that in Pseicdoskusea mediolineata, mihi, I have 

 inadvertently described Theobald's Skusea medio/asciata, the distinctien 

 between the two genera being not the toothed ungues, but the long palpi. 



ACKNOWLEDGMENT. 



The Curator begs to acknowledge with grateful thanks the receipt of 

 a box containing 87 specimens of Cuban Lepidoptera, Rhopalocera and 

 Sphingidse, sent by Mr. Charles T. Ramsden, Guantanamo, Cuba ; they 

 form a very welcome addition to the collections of the Entomological 

 Society of Ontario. 



Note. — The Rhachidorus Se?ni?ii, Krauss, Orth. Austr. and Malay i- 

 schen Archip., p. 765, pi. LXVII, figs. 13, i3a-b (1902), from Queensland, 

 was inadvertently omitted from my fascicula on the Decticin?e in 

 Wytsman's Genera Insectorum, which has just appeared. 



Too late for recording in the above-mentioned work, I find my 

 Platyckis Fletcheri^ described from a $ from Canada, belongs to the 

 genus Idiofiotus, and is the same as my /. brevipes, described from an 

 alcoholic $ from Arctic America. The discovery of this synonymy is due 

 to Dr. E. M. Walker, of Ontario, who has taken both sexes of this insect.
