from a point just behind the last molar towards the inferior 

 edjje some distance in advance of the angular process. 

 Below and in front of this ridge there is another large 

 depression. In all other bears the hollow of the coronoid 

 is l)ounded inferiorly l)y a crest running horizontally for- 

 wards from the angular and curving upwards on a level with, 

 or in front of, the anterior edge of the root of the coronoid 

 process, and the adjoining surface of the mandibular ramus 

 lias no depression. Perhaps in Tremardus the depression 

 of the coronoid (masseteric fossa) may be described as very 

 laige and completely divided by a bony ridge into an upper 

 and a lower })orti()U by the above-mentioned crest of bone, 

 but the musculature of this region requires, I believe, 

 workinsf out. 



X. — Xote on the Subgenus Paradownesia, Gestro. 

 By S. Maulik, B.A. (Cantab.), F.E.S. 



In the 'Annali del ^luseo Civico di Storia Naturale di 

 Genova' (serie 2a, vol. xx. (xl.), 3 Nov., 1899, p. 220), 

 Dr. Gestro has published a note on the genus Dowuesia, 

 founding Paradoicnesia as a subgenus of it. The characters 

 on which he establishes the subgenus are stated as follows: — ■ 

 "(1) Vua fades mo\to diversa, dipcndente della forma piu 

 allungata e piu stretta ; (2) dagli elitri convessi, piii stretti all' 

 apice die alia base, nou piii larghi del protorace e con scultura 

 leggera; (3) II capo e troncato in avanti e si avanza alquanto 

 al di la degli occhi con una sporgeuza larga rettangolare 

 che in parte copre il piimo articolo delle antenne.'^ Then 

 Dr. Gestro goes on to remark that this conformation of the 

 head is not found in any species of true Do?rwe6fa, including, 

 of course, the type. I agree with him that Z). longipennis, 

 Gestro (the iy\}eoi Paradownesia) and other forms which he 

 has described under it ought to be separated from Doivnesia, 

 with which they have no affinity. But I see no reason why 

 they should form a subgenus oiDownesia at all. Judging from 

 the figure and description of D. longipennis (Ann. Mus. Civ, 

 Stor. Nat. Genova, vol.x. (xxx.),Kov. 1890, p. 244, and Nov. 

 1899, p. 220), and examining Paradownesia fruhsturferi, 

 Gestro, of which a cotype exists in the British Museum, and 

 also another specimen which bears a label in Dr. Gestn/s 

 liandwriting, determining it generically as Paradownesia, I 

 am of opinion that this subgenus should be a synonym 

 of Leptispa. My first reason is that the characters that 

 Dr. Gestro selects for erecting Paradownesia are found in
