anterior and posterior margins^ but become obsolete in the 

 median part of tLe disc. A median longitudinal impression, 

 abbreviated before and behind, is sometimes present on the 

 disc, and the b.ise has a slight impression on either side 

 about halfway between the middle and the posterior angle. 

 A series of punctures extends across the thorax immediately 

 behind the front margin ; it continues as an impressed 

 series along each side, in the front part running parallel to 

 the lateral margin, but behind curving inwards away from 

 the side and approaching the basal impression. Scutellum 

 smooth. Elytra entirely and closely covered with very 

 numerous tine striolse, elongate and rather irregular in 

 direction, appearing to form a network of elongate meshes, 

 though few, if any, of the striolae are actually connected 

 with one another ; each elytron has sis very fine striae on the 

 disc, reaching almost to the ba^e, though strise 1 and 3 are 

 extremely fine in front, stria 1 (the sutural stria) being 

 sometimes obsolete in its anterior portion ; striae 2, 4, 6 are 

 a little more strongly marked and finely punctured ; striae 5 

 and 6 are closer together than the others are to one another ; 

 the striae do not quite I'each the apex, 2 and 4 are a little 

 shorter than 1, 3, and 5, and 6 is the shortest of all; the 

 apical portion of the elytron beyond the ends of the striae 

 bears some punctures; there is no submarginal stria, but a 

 series of punctures, rather difficult to see, close to the margin, 

 Meiasternum without striolae or punctures. Hind cojoe and 

 abdominal segments 1 and 2 with numerous fine striolae, 

 segments 3-6 smooth.

A sculpture of longitudinal striolae on the upper surface 

 is very characteristic of the genus Aylymbus. JNlost of the 

 previously known species have only the striolae and no striae 

 on the elytra, but A. bromeliarum has both striae and striolae. 

 In this one character it resembles the two Abyssinian species 

 [A. gestroi Sharp and A. brevicornis Sharp) more than it 

 does the South American species ; but they only have four 

 strige on each elytron, while it has six. In fact, A. bromeli- 

 arum is unlike any of the other species of the genus. 

 Several of the Soutli American species which I have seen in 

 Dr. Sharp's collection are very different ; in addition to 

 being devoid of elytral striae, they are narrower and much
