having a fairly distinct median longitudinal impressed line ; elytra as 

 deeply punctured as the prothorax, but the punctures are more 

 closely set and the pubescence is denser ; upper side of abdominal 

 segments glabrous, very closely and deeply punctate, the apical 

 margin of the second segment is laminate with the angles produced 

 into an arcuate spine reaching the apical margin of the third 

 segment, the ultimate one bears four small tubercles. 



This species differs from M. uncinata in the still shorter antennae, 

 the intermediate joints of which are also more transverse, the pro- 

 thorax nearly straight laterally, and the deeply punctate surface of 

 the upper side of the abdominal segments. 



Length 6 mm. ; width 1| mm.

This species is not unlike M. terminata, Boh., but more massive, 

 the intermediate antenna! joints are wider in proportion to their 

 length and not set so close to each other as in M. tcnninata, the 

 second abdominal segment of which is simple in the male. 



MYRMEDONIA PUNCTICOLLIS, n. sp. 



Male : Testaceous-red, with the upper side of the abdomen some- 

 what ferruginous, head fuscous, elytra with a sutural, broadly trian- 

 gular, light fuscous patch, antennae ferruginous, with the exception 

 of the three basal joints which are rufescent, frontal part convex in 

 the anterior part, very plainly impressed in the vertex, very little 

 prolonged behind the eyes ; antennae reaching to about the median 

 part of the prothorax, the three basal joints are normal, fourth and 

 fifth obconical, sixth to tenth transverse, sub-moniliform, set some- 

 what close to each other, eleventh equal in length to the two pre- 

 ceding taken together, slightly tapering but not acuminate at the 

 tip, those joints are densely pubescent and setulose ; prothorax 

 plainly narrower in the posterior than in the anterior part, with the 

 outer angles rounded, the hind ones more broadly than the anterior, 

 sides slightly sinuate laterally towards the posterior angle, somewhat 

 convex in the centre not depressed laterally, glabrous, extremely 

 finely aciculate but also punctulate, the punctures fine and sorne- 

 what broadly separated, and in addition to these there are on 

 each side two conspicuous setigerous pores, the siab-median is 

 situated nearer the outer margin than the centre of the disk, the 

 other is situated slightly past the centre, but nearer to it than to 

 the outer margin ; elytra broader than the prothorax, sparingly 

 punctulate as in the prothorax, very sparsely pubescent, and
