106 Kev. H. S. riovliam's AV«.s- on the 



thing I am acquainted with, it appears to be cleft and developed 

 into two lateral plates, these are completely covered by the 

 dorsal plate which is convex and sulcate externally. 

 Hab. Sarawak, (Saunders). 



Omudius ant/itdicep.s, n. sp. 



Elongatus, sub-parallelus, nigro-piceus, antennarum articulis 

 duobus basalibus et ultimo, tarsisque pallidis ; elytris fasciis 

 dual)us arcuatis, apiceque albida, griseo sericeis. Long. lin. 5. 



Allied to the preceding ; head with the eyes of the width of 

 the thorax, the latter twice as long as wide, opaque, obsoletely 

 constricted before and behind, elytra having the sides parallel, 

 apex simply rounded, pale, the rest pitchy or fuscoiis, obsoletely 

 punctate-striate, strife entire. Underside, legs, and antennae of 

 the colour of the body, with the exception of the tarsi, and two 

 basal and the apical joint of the antennae. The latter are 

 simple as far as the sixth joint, from whence they are widened 

 and compressed. Legs very long. 



Hab. Sarawak, Borneo, (Wallace). 



OltK. It will be seen from the above description that this 

 species, though resembling c/j/utdricus, differs from it in many 

 particulars, notably in the width of the head, and structure of 

 the antenuct, which are not strongly serrate. In the single 

 specimen I liave the alidomen is simple. 



OmadiuK abscissas, n. sp. 



Elongatus, ferrugineus, nitidus, capite, prothorace, elytrisque 

 nigris ; his l)asi, apice fasciaque abbreviata mediana tenui rutis. 

 Long. lin. 



Allied to 0. prloceroides, Thoms., but smaller, and the elytra 

 with series of punctures, of which those near the base are large 

 and irregular, while the remainder, extending from the red basal 

 portion to the middle, are very fine and obsolete. Near the 

 middle of the elytra is a very narrow arcuate fascia reaching 

 neither the margin nor the suture, the apex is obscurely red, but 

 the black of the elytra shades oft" into this colour. The labrum 

 is yellow, and the epistoma clothed with yellow hairs as in 

 prloceroides ; front of the usual width between the eyes, i.e., 

 they are only separated by a narrow band, thorax oblong shin- 

 ing. Legs, with the cox«, red.
