anterior and posterior margiiis^ but become obsolete in tlie 

 median part of the disc. A median longitudinal impression, 

 abbreviated before and behind, is sometimes present on the 

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

 about halfway between the middle and the i)Osterior 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. Scutelluni 

 smooth. Elytra entirely and closely coveied 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 striolse are actually connected 

 with one another ; each elytron has six very fine strise on the 

 disc, reaching almost to the base, though striae 1 and 3 are 

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

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

 a little more strongly marked and finely punctured ; strise 5 

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

 the strice do not quite reach 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 strise 

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

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

 Metasternum without striolse or punctures. Hind co.va and 

 abdominal segments 1 and 2 with numerous fine striolae, 

 segments 3-6 smooth.

A sculpture of longitudinal striolse on the upper surface 

 is very characteristic of the genus Aylymbus. JNlost of the 

 previously known species have only the striolse and no strise 

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

 In this one character it resembles the two Abyssinian species 

 {A. yestroi Sharp and A. brevicornis Sharp) more than it 

 does the South American species ; but they only have four 

 striae 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 South 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
