NOVITATES ZOOLOQICAE XXIII. 1916. 253 



less heavy, the upper two almost effaced, the grey discal line usually less promi- 

 nent and more dentate, and the lines following it on the distal side less developed 

 than in E. aper, the proximal portions of the zigzag line more or less obsolete, the 

 admarginal line less distinct and the brown-black fringe-spots of both wings 

 larger and more sharply defined. Moreover, the forewing is a little narrower in 

 E.guttiwntris, and its distal margin slightly less convex. The tenth tergite of the <$ 

 is longer and slenderer ; the hook of the harpe narrower, and the hook of the penis- 

 sheath broader. 



11. Sphinx separatus melaena subsp. nov. 



c? ? . Colore satnratiore a S. s. separato distincta. 



Hab. Guerrero Mill, Hidalgo, Mexico, 9000 ft. (Mann & Skewes), six <5 <S 

 received from JB. Preston Clark ; and Cuemavaca, Mexico, September 1904 

 (Dr. Gadow), one ? . 



The ground-colour deeper grey than in S. s. separatus, the black markings of 

 the forewing contrasting somewhat less with the ground, and the whole insect 

 appearing more black both above and below, the underside of the body being 

 especially dark-tinted. 



S. istar R. & J. (1903) occurs in the same districts ; it is easily distinguished 

 from S. s. melaena by the pronotnm not bearing two yellow spots and the fringe of 

 the hindwing being much more strongly spotted with black. 



The species of Sphinx were dealt with in our " Revision " under the name of 

 Hi/loicus. 



12. Sphinx ligustri nisseni subsp. nov. 



<S. Alis auticis fascia grisea diffusa submarginali lata, posticis fascia nigra 

 media cellulae contigna. 



Hab. Algeria : Hammam Meskoutine, April 22, 1914 (Dr. Nissen), one c?. 



This is the first Algerian specimen we have seen, and apparently the first ever 

 obtained in Algeria. It came to the camp near the quarry situated about two-thirds 

 of the way from the hotel to the subterranean lake. 



The specimen resembles dark European examples. The clayish tone which 

 pervades the grey costal area of the forewing in European specimens is absent ; the 

 two grey snbmarginal lines situated on the distal side of the black submarginal line 

 are merged together ; the first and second black bands of the hindwing are broad 

 and united from close to the cell to the abdominal margin, the median band touching 

 the cell-apex both above and below ; the black snbmarginal band is broader than 

 the red discal band, and the blackish-grey marginal space is slightly broader than 

 in European examples. 



The underside is rather darker than in average European individuals ; the 

 diffuse black discal band, which in European examples is composed of two bands 

 united posteriorly, is uniformly black, not showing a separation into two bands. 

 The black median band of the hindwing is widened below M 2 , and the grey band 

 placed at its outer side is less conspicuous than in S. I. ligustri. 



13. Amplypterus donysa dariensis subsp. nov. 



Amplypterus donysa, Rothschild & Jord., Nov. Zool. ix. Suppl p. 185. no. 149 (1903) (pt. ; Chiriqui). 



We have now four males from the Southern Faunal district of Central America, 

 three being from Costa Rica and one from Chiriqui. All four are distinguished by
