5i'2 LOMAI'TEHA TRISTIS. 



The elytra at the base hardly broader thau the base of 

 the thorax , uarrowiug towards the apex where they are 

 uarrowly notched and pointed at the suture. The shoul- 

 ders and apical tubercles smooth , the latter with only a 

 few punctures. A faint costa, bordered on the basal half 

 of the elytra by rows of short transverse striae , is situated 

 at a distance of one third of the width of the elytra 

 from the suture ; the space between this costa and the 

 suture is diffusedly covered with transverse punctures on 

 the basal half of the elytra; behind the middle the punct- 

 ures become confluent, thus forming slightly oblique striae; 

 between the costa and the lateral margin the elytra are 

 densely and transversely striated; between the apical 

 tubercle and the suture the striae are directed obliquely. 

 Along the basal half of the suture and the median thora- 

 cical lobe there is a row of deeply impressed irregular 

 punctures on the elytra, Pygidium concealed under the 

 elytra, obtuse, strongly transverse; its whole surface trans- 

 versely and concentrically aciculated. 



The pro - and metasternum longitudinally striated ; 

 the mesosternum irregularly striated, the striae intermixed 

 with punctures , its middle as well as the sternal process 

 smooth, with a slightly impressed longitudinal median 

 line ; the sternal process narrow , elongate , slightly curved 

 upward towards the apex. The abdomen shallowly punct- 

 ured; on the middle the punctures are very fine, on the 

 sides they are larger and more or less semicircular; on 

 the last ventral segment the punctures are large and deep. 

 The femora are transversely, the tibiae more or less lon- 

 gitudinally striated; the striae on the latter intermixed 

 with large punctures; the anterior tibiae with three lateral 

 distinct teeth, the first of which is very small and placed 

 in the middle of the outer margin ; the intermediate and 

 posterior tibiae longitudinally excavated on the inside, 

 provided on the outside of their apical portion with a 

 distinct notch , forming , especially on the posterior pair, a 

 small blunt tooth about one third from the apex , and ter-
