a little short of the anterior margin of the prothorax ; antennae 

 reaching nearly the base of the prothorax, and with the six dilated 

 and pubescent apical joints very little longer, taken together, 

 than the five basal ones, the third of which is longer than the two 

 preceding; prothorax with the anterior and basal parts rounded 

 laterally, and having thus the appearance of being somewhat 

 ampliated, plane on the disk, but with a shallow, median, longi- 

 tudinal impression which is deeper in the posterior part, the lateral 

 margin is fine and not reflexed, the basal one has a deep sulcus 

 running parallel with it ; scutellum impunctate ; elytra cylindrical, 

 narrowed in the posterior part, deeply punctate-striate, the intervals 

 strongly convex and impunctate ; abdomen closely punctulate, basal 

 part of the three abdominal segments strongly striolate longitudinally ; 

 legs closely punctulate ; femora plainly thickening towards the 

 apex. 



Length 19^ mm. ; width 4-i- mm.

STRONGYLIUM ALGOENSE, n. sp. 



Very closely allied to S. discrepans ; it is also black and almost 

 opaque ; the eyes are widely separated and the frontal furrow very 

 strongly arcuate ; the antennas are longer, the joints more elongated, 

 the dilated apical ones less closely set ; the prothorax is slightly 

 more ampliated and rounded laterally in the middle, there is a 

 faintly raised median line which is, however, slightly impressed 

 in the anterior part, and the punctuation which, both on the head 

 and prothorax is finer than in S. discrepans, is hidden by an opaque 

 tinge ; the elytra are cylindrical, highly costate, the costas tectiform, 

 and deeply punctato-striate, the punctures impinge on either side 

 of the costae ; under side as in S. discrepans. 



Length 15 mm. ; width 5-J- mm.

STRONGYLIUM IMITATOR, n. sp. 



Bright metallic green ; elytra testaceous-red, also metallic, an- 

 tennae black ; head deeply and closely punctured in the anterior 

 part, more coarsely in the posterior, eyes broadly separated, arcuate 

 frontal impression deep ; prothorax slightly attenuate laterally in 

 the anterior part for about one-third of the length, parallel thence 

 to the basal part, the angles of which are somewhat rounded, the 

 lateral margin is obliterated, the basal one is grooved and not sharp,
