70 THE CANADIAN ENTOMOLOGIST. 



Syjitomis abdominalis, n. sp. 



$ . — Antennae deeply pectinated ; head and thorax black. Colour 

 black, suffused with blue metallic scales. Primaries dark brownish, 

 opaque, with two large oval semi-transparent spots in the discoidal area, 

 the largest towards the inner angle. 



Secondaries black without any ornamental markings whatever ; abdo- 

 men deep maroon, except the two last segments, which are black. Under- 

 side the same as above, except that the entire abdomen is light carmine, 

 and has a very narrow black lateral stripe on each side ; legs light brown. 

 Exp., (J , i8 mm. 



Mr. G. B. Nasmyth has obtained but one example of this beautiful 

 and unique species at Grand Ses, Liberia, W. Africa ; the type is in my 

 collection. 



Fachypas Nasmythii, n. sp. 



$ . — Antennas fawn-brown, pectinations much darker ; head and 

 thorax fawn-brown ; the latter with a darker brown stripe running its 

 entire length, similar to that of P. Hojirathii, Dewitz, and P. subfascia, 

 Walker. Abdomen, on the upperside the first four segments are of a 

 very light brown, the rest, including the underside, is of a lovely ferrugi- 

 nous colour. Primaries light brown, median limbal area dark or chestnut- 

 brown ; costal inner space slightly shaded with dark-brown, similar to the 

 two darkish marks which are so conspicuous in P. subfascia^ Wlk. ; there 

 is also a dark-brown band, almost black, running through the entire width 

 of the forewing, but not inclined so much as it is in subfascia. 



Secondaries, basal area whitish and thinly clothed with scales, which 

 gives this space a semi-transparent appearance ; the outer marginal space 

 has a broad brown band, darker inwardly, but much lighter on the outer 

 margin ; anal margin the same colour as the basal area. Underside of 

 thorax dark brown ; the legs are of the same colour. 



Underside of primaries, costal space as far a^ the limbal area, light 

 fawn ; limbal area dark brown, with some light shading in the apical 

 space ; basal part on the inner angle much paler than the rest of the 

 wing. Underside of secondaries same as above, except that the costal 

 area is shaded with ferruginous. Exp., 51^ inches. Type in my collec- 

 tion. Habitat, Cape Palmas, W. Africa. 



At first sight this noble creature bears a great resemblance to Pachy- 

 pas subfascia^ Walker, but having before me Dr. Dewitz's paper, which 

 was published in the Nova Acta. Band, XLII.,and which has an excellent 

 figure of Mr. Walker's subfascia on PI. 2, F. 12, I cannot believe other- 

 wise than that I have a new and undescribed species to deal with ; and 

 I have named it in honour of its discoverer. Mr. Nasmyth took but two 

 examples of this grand moth, which, I am safe to say, is the giant of the 

 genus. One specimen is in my collection, the other in that of the Rev. 

 Dr. W. J. Holland, Pittsburgh, Pa.
