New Genera and Species of Neolropical CHrculionidae. 193 



Genus Compsus Sclili. (i82G). 



It may be v>'ell to note here that the following species 

 described by Pascoe (1880) in the genus Eustales must 

 be referred to Compsus : — E. sejxinctus (apparently very near 

 6*. alternans Kirsch), E. comeies (very near C. adawMntinus 

 Kirsch) and E. coruscus. 



Compsus armatissimus, sp. n. (Plate III, fig. 4.) 



^$. Integument black, densely and uniformly covered with 

 creamy white or pale buff scaling (usually with a slight brassy or 

 coppery reflexion), except the tips of the tubercles on the elytra, 

 which bear brown scaling, and two narrow undulating dorsal Inov* n 

 stripes on the pronotum, which are continued on to the head behind 

 each eye. 



Head shallowly constricted behind the eyes, the forehead slightly 

 tumid on each side and with a very deep median fovea, which is 

 connected with the rostral furrow. Rostnuii as long as its apical 

 width, strongly dilated from base to apex; the basal half with a 

 broad shallow median furrow, which widens out anteriorly into a 

 broad triangular impressed space, the apical area being very abruptly 

 and steeply declivous and deeply excavate; the epistome steeply 

 sloping, bare, a,nd without any limiting carma; in the basal half 

 on each side a deep impression in front of each eye and a longer 

 oblique one beyond that, the scales in this area being very densely 

 packed and suberect; rather long stout recumbent or subrecumbent 

 setae along the lateral ridges. Antennae with the scape slightly 

 exceeding the eye, thick, gradually and regularly widening from 

 base to apex, densely clothed with overlapping and suberect scales, 

 and set with stout obliquely raised setae; the funicle with joint 1 

 slightly shorter than 2, 3 longer than 4, and 4-7 subequal and a 

 little longer than broad; the club a little longer than the throe 

 preceding joints, dark brown. ProLhorax as long or nearly as long 

 as broad, subcylindrical, but somewhat narrowed in the apical 

 third ; the lateral margins (as seen from above) irregularly sinuous ; 

 the gular margin shallowly sinuate; the dorsum coarsely plicate, 

 the median area flattened and bounded on each side by a low sinuous 

 iidge, the lateral' area on each side about as broad as the median 

 one; the scales rather shiny, flat and broadly overlapping; the 

 lateral areas with scattered stout subrecumbent setae, but hardly 

 any on the median area. Scutellum pear-shaped, narrowed in front, 

 covered with dense erect narrow scales. Ehjlra oblong-ovate, 

 with a humeral tubercle but without true shoulders, the apices pro-
