520 ME. GUT A. K. MAESHALL ON COLEOPTERA 



the rostrum is not carinate at the base, the two basal joints of the antennal club are of 

 equal length, the elytra on the disc bear punctate sulci witb convex intervals, and the 

 pale sternal patch is confined to the base of the metasternal episternum. 



Mekoleptus squalidus, sp. n. 



? . Niger, sqnamulis terreno-brunneis spatulatis erectis undique indutns ; rostro basi tricarinato; 

 funiculi articulo primo quam secundo paulo longiore ; pvothorace grasse et profunde reticu- 

 lato-punctatOj puvictis a squamulis pro maxima parte conditis, interstitiis passim (prsecipue ad 

 latera) granulis nitidis obsitis, lateribus fortiter rotuiidato, in medio longitudinaliter sub- 

 sulcato ; eh'tris basi denticulatis et transversim granulatis, foveato-sulcatisj interstitio primo 

 deplanato, interstitiis 2, 4, 6 granulis nitidis uniseriatim obsitis, interstitiis lateralibus sparsius 

 granulatis. 



Black, fairly densely clothed with erect spatulate brown scales of varying lengths. 



Eead reticulately punctate, with a deep frontal fovea and short erect scales, the 

 ridge on the vertex shallowly sinuate in the middle. Rostrum with the antennae 

 inserted at about one-fifth from the apex, tricarinate at the base, the outer carinse 

 narrow and very sinuous. Antennce testaceous brown, the first joint of the funicle 

 longer than the second, the club broadest in the middle. Protlwrax as long as broad, 

 the sides snbparallel for a very short distance from the base, then very strongly 

 rounded, broadest a little beyond the middle ; the upper surface with large deep 

 reticulate punctures, which are more or less hidden by the scaling, the interspaces set 

 here and there with bare shiny granules, these being much denser at the sides, in the 

 middle a shallow longitudinal furrow. Elytra subovate, with the sides slightly 

 rounded, the basal margin broader than that of the prothorax, denticulated and with a 

 transverse row of granules, the upper surface foveato-sulcate, interval 1 flattened, the 

 others slightly convex, 2, 4, and 6 each with a complete row of numerous shiny 

 granules, the lateral intervals with much more distant granules. Legs Avith rather 

 dense elongate suberect scales, the femora coarsely punctate, the tibiee carinate, but 

 the carinse more or less hidden by the scaling. 



Length 5, width 2^ mm. 



Launch Camp, Setakwa River, Oct. 1912 {G. JBoden Jiloss); 1 5- (^J/iJe of the 

 sjjecies.) 



Described from a single specimen. 



This small and relatively broad species differs from all the known forms except 

 3L tuberculosus Faust (Ann. Mus. Civ. Geneva, xl. 1899, p. 64) in having the 

 prothorax punctate ; but in the latter species the punctation is remote and shallow, 

 and the prothorax bears four rows of setose tubercles ; the elytra are also very 

 differently sculptured, being only faintly punctato-striate, and interval 3 bears three 

 pubescent tubercles.
