33O MEMOIRS ON THE COLEOPTERA 



abdomen and the anterior spiniform tibial teeth nearly similar; 

 pygidium always nude, with a triangular spot of tomentum at each 

 side. Length (cf 9 ) 15.0-17.0 mm.; width 9.2-10.0 mm. Mexico 



(Guerrero). Three examples *binoculata n. subsp. 



B Nearly similar to biguttata in every way but a little smaller and less 

 stout, the clypeus more rapidly and obliquely acuminate at apex, 

 the latter less broadly obtuse, feebly bilobed; pronotum with the 

 sculpture similar but with the punctures not quite so coarse or 

 dense laterally; elytra exactly as in biguttata and with the flanks 

 closely, transversely lineate with tomentum posteriorly to the 

 large apical spot, which, similarly, has a very small black point 

 toward the sutural angles, but here, there is a longitudinal line of 

 short transverse tomentose spots from the inner end of the long 

 submedial tomentose fascia to the solid apical area, this longi- 

 tudinal line of spots sometime? paralleled by another partial series 

 just external to it; elytral hairs minute but easily seen; pygidium 

 solidly tomentose as in biguttata; anterior tibiae in all the specimens 

 at hand having the three teeth much shorter and very obtuse at 

 their tips, probably an effect of wear, but in a singularly constant 

 manner in all the six tibiae of the three cotypes. Length (cf 9 ) 

 13.7-14.8 mm.; width 8.2-8.7 mm. Guatemala. 



*biplagiata n. subsp. 



Body oblong-oval, almost as in biguttata in its shining lustre, glabrous 

 upper surface and elytral and abdominal tomentum, but rather more 

 elongate and black throughout above; head nearly similar, with a 

 transverse basal line of stiff pale hairs; pronotum similar but with 

 the punctures more broadly subobsolete medially and, toward the 

 sides, shallower, forming oblique lines and having longer and much 

 more distinct hairs; scutellum similar, perfectly smooth; elytra with 

 similar sculpture and subobsolete costae, but with the sparse punc- 

 tures everywhere deeper, especially on the flanks, where there are 

 about two short broad, inwardly projecting spots of tomentum, at 

 basal third to two-fifths, and a broad irregular line from the margins 

 inwardly nearly to the suture distinctly behind the middle, also 

 with a large solid apical area, usually having a minute black spot as 

 in biguttata; pygidium solidly tomentose, except medially toward tip; 

 anterior tibiae with three acute teeth nearly as in biguttata, except 

 that they are more uniform in size, the upper larger and the two 

 lower elongate and spiniform. Length (cf) 15.0-15.3 mm.; width 

 8.7 mm. Mexico (Villa Lerdo in Durango), Hoege. 



*lineoligera Bates 



8 Body rather narrowly suboval and notably convex, shining and deep 

 black throughout, except slightly more than basal half of the elytra, 

 which is abruptly bright red, excepting a large transversely quadrate 

 basal spot involving the scutellum, which is black; upper surface 

 with minute sparse erect hairs, longer on the pygidium and rather 

 long, coarse, pale and conspicuous on the sterna and sides of the 

 abdomen; head deeply and densely punctate, the clypeus feebly 

 trapezoidal, with moderately rounded angles, the apex very feebly 

 reflexed, obtuse, just visibly sinuate medially; prothorax a third or
