NOVITATES ZOOLOGICAE XXI. 1914. 231 



of an obtuse tubercle bearing a slightly prolonged brownish pubescence. The third 

 interspace of the elytrum is raised into a subbasal ridge, which is black anteriorly. 

 The snbapical callosity of the elytrum is but slight, though quite distinct. 



35. Anthribus tenuicornis spec. nov. 



c??. .4. cillio similis, magis umbrinus ; antennis mnlto tenuioribus, articulo 

 3'° longiore quam 5°, ultimo acuminato, in utroque sexa clava setis brevibus erectis 

 instructa, antenna cJ infra pilosa, elytro tuberculo snbapicali magis distincto 

 instructo, abdominalibus segmeutis 1°— 1° maris maculis medianis e tomento sat 

 longo compositis notatis, segmento 5" depresso, subtrancato. 



Long, (cap excl.) : 13-14 mm. 



Two pairs from Kondu^. 



Darker than the previous species, the grey pubescence of the upperside less 

 white, the central areas therefore not contrasting so much with the sides as in 

 A. cillius. The brown basal and median spots of the tibiae are larger, and the 

 grey pubescence of segments 2-7 of the antennae ((? ?) is dense only at the apices, 

 segment 8 being entirely greyish white only in the ?. 



The antennae are much thinner than in ^4. planatus Jord. (1004), and cillius; 

 they bear numerous thin erect hairs on the inner surface in the S , the antenna of 

 the ? also not being entirely devoid of such hairs. The short, stiff bristles of the 

 club are more prominent than in cillius. Segment 3 is longer than 5. The 

 elevated parts of the pronotum are less raised than in cillius, and the angle of the 

 carina is decidedly more obtuse, more rounded than in that species, the third and 

 fifth interspaces of the elytrum are more convex and the snbapical callosity much 

 more elevate. 



The pubescence of the abdominal segments 1-4 (<?) is denser and longer in 

 the centre than elsewhere, but does not form real tufts, nor is the patch on the first 

 segment so sharply defined as in A. planatus and cillius ; the fifth segment of the 

 (? is somewhat concave, with the apical margin slightly truncate. 



We take the opportunity of describing the following species from the collection 

 of the Tring Museum : 



36. Anthribus haplosoma spec. nov. 



(??. -4. tenuicorni valde afiinis, antennis crassioribns {S), pronoto iu medio 

 eodem colore ut ad latus, breviore quam in A. tenuicorni, elytrornm interstitiis 

 alternis albo-griseo notatis, tuberculo snbapicali minus elevato, abdomiue {i) 

 absque maculis medianis tomento compositis, segmento 5" hand impresso. 



Long. (cap. excl.) : 8-13 mm. 



A series from the Kuilu River, French Congo. 



The pronotum is less impressed than in the two previous species and almost 

 uniform in colour, apart from two (or one) greyish white dots at each side of the 

 depression, a short greyish white median stripe at the apex and an ill-defined patch 

 in front of the scutellum. The alternate interspaces 1, 3, 6 (etc.) of the elytra are 

 tessellated with greyish white and black, the greyish white colour being particularly 

 conspicuous in the antemedian depression and at the commencement of the apical 

 declivity. 



The greyish white markings are sometimes not prominent.
