Free border of firsl tergite with the usual ten marginal areas. Elsewhere 

 the tergite is strongly eonvexry elevated, and covered with numerous, closely 

 arranged prominently protruding rounded tubercles of which eight are I 

 than the others. Other tergites crossed with four ti rows of closely 



arranged tubercles of which the mosi anterior and most posterior are most 

 poorly developed and the posterior in particular are often incomplete; the 

 usual two submedian crests formed by rows of larger tubercles, three m each 



row on each plate, not very conspicuous, no similar prominent lateral row on 

 each side; two row- of small tubercles between these. Lateral margin of 

 keels of second and of seventeenth, eighteenth, and nineteenth tergites tri- 

 lobed, of others bilohed, the emarginations weak. Pore-papillae at apex of 

 deeper emarginations in caudolateral corners, subvertical to surface. Last 

 tergite prominently exposed from above, the margin crenate, showing BIX 

 lobes; two smooth, continuous ridges corresponding to the median rows of 

 tubercles of other plates, no tubercles elsewhere. Tubercles of median rows 

 on penult tergite not more prominent.

In coloration like the preceding species. It is a somewhat smaller 

 and more slender form with similar structure and appearance. The 

 keels are a little narrower and slightly less depressed. The transverse 

 rows of tubercles are alike though with fewer tubercles in a row, 

 normally twelve, as against fourteen in the average of T. conformans. 

 The tubercles form distinct longitudinal rows whereas in conformant 

 tiny are more singular. The tubercles of the two submedian longi- 

 tudinal rows are much less prominent, being scarcely more elevated 

 than the others on many of the tergites; correspondingly the ridges 

 of the anal tergite are much lower and the lobes at their caudal ends 

 do not project caudad of the adjacent lateral ones as they do in most 

 species, the line of the apices of the four caudal lobes being thus nearly 

 straight, the emargination separating off the anterior lobe on each side 

 shallow the anterior lateral lobe equalling or exceeding in length the 

 one caudad of it, whereas it is shorter in T. conformans. The lobation
