Five specimens, varying in the development and colour of the elytral fascia. The 



unimpressed intercoxal portion of the presternum, the very sparsely punctured 

 metasternum, and the gradually widened basal portion of the rostrum are noteworthy 



in this insect. The last ventral segment is almost bare in both sexes. 

 The Tabernilla example was captured in May 1907, and the two from Caldera Island 



in April 1908

sulcata beneath, the frontal fovea small. Prothorax a little longer than broad, narrowing from near the 



moderately broad, opaque above ; black, the elytra each with a transverse, somewhat curved 

 outwardly widened, sanguineous median fascia extending from the first to the seventh stria. Rostrum 

 stout arcuate, about two-thirds the length of the prothorax, feebly punctate, smooth at the tip, shallowly 



base, slightly depressed and sparsely punctate on the disc behind, the base strongly bisinuate. Scutellum 

 triangular, hollowed anteriorly. Elytra much wider than the prothorax, subcordate, finely punctate- 

 striate, the interstices very minutely punctured down the middle. Pygidium with a short crest at the 

 tip. Beneath somewhat closely punctate laterally. Prosternum hollowed between the coxae anteriorly. 

 Femora with a few short minute hairs beneath. Tibiae shortly, finely ciliate within.

Two specimens agreeing perfectly with Olivier's coloured profile-figure of Calandra 



faseiata. This species may be known by its subfusiform shape and the narrow, 

 incomplete, sanguineous median fascia of the elytra. It is more elongate than the 



somewhat similarly marked M 



more slender rostrum, the pro- 



sternum convex between the coxae, and the anterior coxse themselves a little more widely 

 separated), the metasternum smoother at the sides, and the elytral fascia less developed 

 and placed (as in M. ochreofasciatus) at a greater distance from the base. This 







has been quoted as from N. A
