DESCRIPTIONS OF THREE NEW SPECIES OF LEMA. 241 



constricted behind, antennae not quite reaching the middle of the 

 elytra, the first joint rufous, second short, third shorter than fourth ; 

 pubescent from first to end, which is slightly fuscous, thorax smooth 

 polished, rather strongly constricted behind the middle, a few very 

 fine punctures at the anterior angles, which are obsolete ; also two 

 fairly regular rows on the disk (with scattered ones between), but 

 all very fine and obsolete after the middle ; scutel fulvous, elytra 

 shining violet, the punctures arranged in striae but not impressed, 

 and obsolete behind, where the striae become plainer, sides parallel, a 

 deep intrahumeral impression and a well-marked transverse impres- 

 sion below the base (where, as usual, the punctures are the largest), 

 the margin thickened at the sides, the yellow colour is confined at 

 the sides to this margin ; it suffuses the tip and is again visible in 

 the scutellar region, but does not extend below the basal depression. 

 It shows, also, very narrowly at base where it connects with the 

 lateral margin. 



My example bears five labels: " Playa Vicente," "Mexico 

 Salte coll.," "12," " n.i.m.," "Jac. 2nd coll." It was unnamed 

 in the Jacoby material. It seems to come near peruana, Jac. 

 (type in my coll.). 



Lema balsas, nov. sp. 



Eufous, elytra dark shining, ccerulean blue, antennae except the 

 basal joints, the posterior legs wholly, and the four anterior tarsi 

 wholly, and tibiae partly, black, body beneath, except the thorax, 

 dark shining, almost impunctate blue-black. Length 8 mm. 



Type, one example, Eio Balsas, Guerrero, Mexico (Wickham) 

 (coll. Bowditch). 



Head with clypeus swollen, nearly smooth, with a deep foveate 

 puncture in the middle ; head not constricted behind the eyes, 

 vertex swollen, transversely strigose with a deep foveate depression 

 in the centre, antennae with four basal joints, smooth, first two 

 rufous, three and four equal, rufous blackish, remainder black 

 pubescent, not reaching the middle of the elytra ; thorax rather 

 short, anterior angles (viewed from above) rather prominent, coarsely, 

 moderately punctate ; also a median row of finer punctures three or 

 four wide, beginning at the anterior margin and running down the 

 middle of the disk, and gradually tapering off to a deep fovea in the 

 transverse depression at the rear ; sides deeply coarctate a little 

 behind the middle, the extreme base narrowly margined, scutel 

 rufous, slightly blackened ; elytra stout, parallel, finely punctate in 

 regular striae (only the sutural being impressed), a well-marked short 

 intrahumeral impression and a deep, transverse basal depression 

 (foveate) and a large lateral, foveate puncture on the edge below the 

 shoulder ; the four anterior tibiae are rufous below, shading into 

 black above, the mesosternum punctured anteriorly. 



I place it near chalybeipennis, Lac. 



Lema wickhami, nov. sp. 

 Rufous, elytra chalybeate blue, lower part of face, antennae and 

 legs black. Length 5 mm.
