{h) Tlif>rc is no distinct scutoUuni; tlie buck of the meso- 

 notiini piL'sents only indistinct I'liirows close to its posterior 

 border, from which the scutellum or the metanotum cannot 

 be recognized. This is well sliown in the photograplj. 



(e) In consequence of this reduction of the distal part of 

 tlie thorax the posterior cox* are placed in contact with the 

 intermediate ones. 



[d) The rudiments of the wings are well developed, being 

 much more than " minute prominences." In the type- 

 specimen they are 2 mm. long, and have a stalk-like basal 

 part and a dilated terminal portion. The rudiments of the 

 lialteres are less developed. 



(«) The back of the mesonotum has a distinct pattern, 

 being reddish yellow, with a broad, longitudinal, complete

blackish stripe, which ends in front of the first posterior 

 furrow. The abdominal pattern, when distinguishable, is the 

 same as in subulatus. 



Additional Note. — Since this was written, I have received, 

 through the courtesy of Mr. Hardy, a female paratype of his 

 Boreoides subulatus. Comparing this specimen with the type 

 of Bor. iasmavietisis, 1 have found that the diflferences in the 

 annulation of third antennal joint and in the position of hind 

 cox« are not constant, being similar in the two species. On 

 the other hand, there are very im|)ortant diflferences in the 

 shape of scutellum, in the length of wing-rudiments, and in 

 the coloration of the back of mesonotum. I find, moreover, 

 that the legs of tasvianienais are considerably more thin and
