Lethaeus maquilingensis sp. nov. 



Elongately elliptical, shining, black; pronotum with a trans- 

 verse, pale yellow basal spot on each side before base of clavus; 

 lateral margins of pronotum, clavus, basal half of corium and 

 an area at its inner apical angle, and male genital segment dark 

 testaceous; a broad diffuse fascia immediately behind middle 

 of corium and a triangular spot occupying its outer apical angle 

 piceous, two oblong spots to clavus and an irregular, sub- 

 triangular, inwardly narro\\ing costal spot before apical angle 

 of corium stramineous, membrane infuscated, less so at apex; 

 antennae fuscous, second joint (except apex) testaceous, base 

 and apex of third joint pale yellowish (fourth wanting) ; ros- 

 trum brownish testaceous; legs piceous, fore and middle tibise 

 and all tarsi testaceous. Head a little broader than half the 

 basal width of pronotum, nearly as long as broad, thickly and 

 very finely punctate above and beneath, each ocellus placed in 

 an impunctate area, anteocular part a little longer than the 

 large eyes, roundedly acutangular, clypeus slightly longer than 

 juga, antennae more than half the length of the body, first joint 

 passing apex of head by more than half its length, second one- 

 half longer than first, third equal to second, rostrum reaching 

 base of third ventral segment. Pronotum rather deeply, trans- 

 versely impressed a little before the middle, lateral margins 

 straight, narrowly laminated, with an erect seta near the apical 

 angles, posterior lobe finely and rather thickly punctate with a 

 narrow, slightly raised, median carina, evanescent before the 

 base ; basal margin a little rounded in front of scutellum, anterior 

 lobe sparingly and extremely finely punctate, with a collar that 

 is terminated behind by an impressed line distinct only toward 

 the sides, being obsolescent in the middle. Scutellum with a 

 percurrent, Y-shaped, almost impunctate callosity, finely and 

 sparsely punctate on the lateral areas, more thickly so between 

 the anterior .branches of the callosity. Corium moderately 

 thickly punctate, median vein simple, arising from behind middle 

 of radial vein. Pectus coarsely and thickly punctate, a trans- 

 verse area to propleura and posterior border of metapleura 

 impunctate, evaporative area extended outward beyond apex of 

 orificium, reaching middle of metapleura, its outer margin 

 straight. Abdomen beneath distinctly and sparsely punctulate, 

 male genital segment vertically impressed behind. Front fe- • 

 mora, in their median part, with a row of four bristles arising
