Liicanoid Colcoptcra. 93 



coupled witli the form and slender character of its legs, 

 and its unarmed posterior tibiae, to consider that this 

 species is perhaps more closely allied to the Cladognathidce, 

 or to the Odontolabidce, the latter having the posterior 

 tibise in both sexes unarmed. The singular anomaly of 

 having the posterior tibiae unarmed in this sex of the 

 Cladognathidce, has fallen under my notice only in two 

 species, Pi-osopocoilus cavifrons and P. approximatus ; 

 nevertheless as a knowledge of the male sex can alone 

 declare its true position, I prefer for the present to 

 locate it temporarily in the fourth section of the genus 

 Dorcus, together with two other insects, the males of 

 which are at present unknown. 



u^yus Jtandiensis, Hope. (PL II. figs. 5, 8.) 



Under some reservation, two insects from Borneo and 

 the Philippines were united (Cat. p. 53) with ^gus Ttan- 

 diensis ; they have, since an acquaintance with a larger 

 series of specimens, been considered as distinct, and de- 

 scribed by M. H. Deyrolle in the Ann. Soc. Ent. Belg. 

 (vide ante, p. 62) under the names of yEgus ogivus and 

 ^gus philippinenHis, from Malacca and the Philippines 

 (the former is also a native of Borneo) . ^gus handien- 

 sis was represented in Mr. Hope's collection by a var. 

 minor, and was placed in his Catalogue as a synonym of 

 u^gus cicatricosus, Wiedemann ; the latter now proves to 

 be the ^gus acuminatus. Fab. The following is a more 

 extended description of yE. Icandiensis : — 



$ . (var. max.) Nigro-brunneus, obscurus, parum 

 nitidus ; mandibulis robustis, arcuatis, ad medium dente 

 obtuso instructis ; capite antice excavato, in medio tuber- 

 culo obtuso armato, lateraliter pone oculos angulatim 

 lobato, vertice piano, lateribus utrinque fortiter et 

 rugose punctatis; prothorace transverse, lateribus rectis, 

 angulis anticis paulo emarginatis, posticis oblique trun- 

 catis ; elytris brevibus, nitidis, parum convexis. 



The male (var. max.) is distinguished from that of ^. 

 phiUppinensis, to which this species is very closely allied, 

 by the truncation of the posterior angles of the thorax, 

 which are scarcely emarginate, by its more convex form 

 in all its developments, by its coarser punctuation, and 

 the brevity of the elytra. The female is also conspicuously 

 shorter and more convex, with the punctuation of the
