XXIII. Additional notes on the genus Hilipus. By 

 Francis P. Pascoe, F.L.S., &c. 



[Read November 6th, 1889.] 



Plates XVI. & XVII. 



For certain preliminary observations I must refer to 

 my paper " On the genus Hiliims, and its Neo-Tropical 

 allies," in the Society's * Transactions,' published April, 

 1881. As far as appearance or facies goes, it will be 

 seen that the species here exhibited differ considerably 

 from one another, and this is so almost throughout the 

 genus. I have seen about 300 species, many of which 

 are still undescribed.* 



In the following list I have, as before, followed Schdn- 

 herr's arrangement — an extremely artificial one, as 

 Lacordaire justly observes, but in the present state of 

 our knowledge the most convenient : — 



The two basal joints of the funicle equal or nearly equal in length. 

 Apex of the elytra rounded. 



Elytra without tubercles or granules. 



Hilipus pardalis. Hilipus Jimbriatus. 



,, excultus. „ Fryi. 



Elytra with tubercles or granules, or both. 



Hilipus validus. Hili^nis decipiens. 



,, ocularis. ,, ohtusus. 



Hilipus lutosus. 



Apex of each elytron pointed or acuminate. 



HilipiHs ludiosus. Hilipus arctu7-us. 



Second joint of the funicle longer than the first. 

 Apex of the elytra rounded 



Elytra without tubercles or granules. 



Hilipus congestus. Hilipus angusticollis. 



Elytra with granules or transversely rugose. 



Hilijnis frontalis. Hilipus polyspilus. 



,, latipennis. ,, lamina. 



Hilipus tetraspilotus. 



* Hilijnis alternans, Guar. (Icon. Eegne An. lus., p. 152), is, I 

 think, from the description identical with H. h'qyporliinoides 

 (Trans. Ent. See. Lond., 1881, p. 75) ; " clavatis," fifth line from 

 the bottom, read elevatis.
