Elytra valdc ahbreriita, vix ditnidiinn nhdomlnis scymmti primi trfjentirr, 

 apice truncata et utrhique hispinosa. Alee ut in gen. Myzomorphus etc. 

 plicatce. Frosternum apice jrroductum, conicum. Mesostcrnum depressum, 

 angustum. Jfefastenii episterna paralhdogrammica, iqnce paulo angus- 

 tata. Pedes valde compressi, asjjei'ati ; tarsis hrevissimis. Antennce 

 (?) corporis dimidiian vix siqyeranfes, siib-ser rates ; arficulo priinobrevi, 

 cylindrico ; 3 — 5 medio valde compresses (3*° ca'teris multo longiori) ; 

 Wmo Irevi, suh-rotundato ; 3- — -7 intus 8 — 11 omnino dense porosis. 



The thorax of tliis extraordinary Longicoru approaches in form 

 that of Purpiiricenus ; but the anterior coxa? are greatly elongated, 

 and lie in transversely elongated sockets like the Prionidce, and there 

 is a trace of lateral rim separating the pronotum from the flanks, lying 

 below the lateral spine and forming an obtuse ridge, so that there is 

 no doubt of its belonging to the Prionidcs family. It differs, however, 

 from the Anacolince (with which at first sight one would be inclined 

 to place it) by the parallelogrammical metathoracic episterna and 

 other characters.

Long. 10 lin., ? . 



Sarawak, Borneo ; one example. The upper-surface is glabrous, 

 the under-surfaco and legs clothed with fine erect pubescence. The 

 head, epistome, eyes, labrum and mandibles are similar in form to those 

 of BTgzomorplius scutellaius 5 , but the palpi arc very different, being 

 shorter, and having their terminal joints tapering to an obtuse point, 

 and the sides of the cheeks terminate in a long spine. The eyes are 

 much more finely granulated. The antenmc are more robust, steel- 

 black in colour, and having a very short scape very slightly widening 

 from base to apex. The abdomen is very similar to that of the ? 

 Myzomorphus ; tumid, with flexible integument and truncated fifth 

 ventral segment. The short elytra are dehiscent at the suture, broadly 

 and obtusely truncated, with a long sharp tooth in the middle of the 

 apical margin, and another near the exterior angle ; like the thqrax 

 and head they are covered with shallow punctures or pits, which leave 

 narrow interstices forming an elegant network when viewed under the 

 lens. The tips of the membranous wings are black.
