Xieng Khouang (April). 



I liave seen only a single male of this species, the smallest 

 yet known of its genus. It is of a peculiarly compact 

 oblong form, with a strongly transverse prothorax, whose 

 greatest width is equal to that of the elytra, and narrowing 

 very little to the shoulders. It is very smootli and shining, 

 with a deep basal furrow, no longitudinal channel, and 

 basal foveie strongly impressed and extending almost to the 

 middle. The elytra scarcely taper bcluTid, and are closely 

 and evenly punctured, but smooth and shining. The legs 

 and antennaj are short and stout, the third joint of the 

 latter conical in shape and little longer than it is broad at 

 the outer end, the succeeding joints all transverse. 



The tibiae of the male are not toothed, but broadly dilated 

 a little beyond the base aiul clothed with close silky pubes- 

 cence towards the extremity. The hind tibia are especially 

 broad from the middle (where they are strongly curved) to 

 the extremity. The middle tibite arc incurved just before 

 the end. 



Emnor])hus austerns, Gerst. Nam Ticne, Upper Mekong. 

 This species ranges from Assam to Cambodia. 



Eumorphus sanguinipes, Guer. This was found by M. Yi- 

 talis in tlie same locality as the last, and has a similar range 

 northwards, but I have not seen it from farther south. 



Eumorphus quadric/uttatus, Illig. Vientiane, Pak Pha; 

 Annam; Tonkin. This is an extremely common insect 

 throughout its range, which extends to Java, Sumatra, and 

 Borneo.
