estendiDg to the sntnre : a secoud black band before the middle, consisting of two 

 angnlated spot;*, joined in the tiipc, bnt separated in a second specimen: this band 

 commences at the margin, bnt does not qnite reach the sntnre ; a third black band, 

 diagonally transverse, commencing at the margin at abont three-fourths of its 

 length from the base ; it is much shorter than the middle band, and is also com- 

 posed of two angnlated spots joined together; it is continued on the margin into u 

 narrow border which reaches the apex and extends a little way up the suture. 



Under surface and legs black ; soles dark brown. 



Long. 28 mm.; lat. hum. 11 mm.; antennae 17 mm. 



Hah. Taken by myself at Paramba, Ecuador, April 1897, at an elevation of 

 3500 feet. 



HISPIDAE. 

 3. Alurnus costalis sp. nov. 



Thorax thickly covered with a grey pubescence ; transversely deeply depressed, 

 rngosely punctate, strongly convex in front, sides slightly depressed at apex : an 

 obtuse tooth at posterior angles. 



Antennae black, half the length of the body, third joint more than twice the 

 length of the fourth. 



Scutellum black, coarsely punctate. 



Elytra much broader than thorax, margined, slightly sinuate below the 

 shoulders; humeral process well developed; six strongly marked costae, distributed 

 as follows : the first commencing at the base and running along the whole of the 

 sntnre ; the second also commencing at the base, confluent with the first for a little 

 distance, then running independently for about a fifth of the length of the elytra, 

 where it again merges into the first; the third starting from the base of the elytra 

 at the same point as the first and second, inclining towards the suture for about half 

 its length, whence it runs i)arallel to it; the fourth also starting from the base, but 

 not becoming prominent until passing the humeral process ; the fifth commencing 

 behind the humeral process, the sixth at the outer base of the shoulders. All the 

 costae show a tendency to converge towards the apical angle, but are lost before 

 reaching that point; the first, third, and fifth are the longest. The spaces between 

 the costae are thickly punctate, the coarsest punctures being at the base; there 

 are occasional punctures in the costae themselves. The elytra are ochre-yellow 

 in colour for slightly more than half their length from the base, the remainder 

 being blood-red; the costae, however, are yellow for their entire length, running over 

 the red portion of the elytra in the form of stripes. 



Legs and under surface black; soles reddish brown. Under surface and tibia 

 thinly covered with a greyish pubescence. 



Long. 33 mm.; lat. hum. 12 mm.; antennae 13 mm. 



Hah. West coast of Colombia and Ecuador. 



The bipe, now in the possession of the Hon. W. Rothschild, was taken by me at 

 Juntas, Rio Dagua, Colombia, in 189.5, crawling on a tree-trunk, near the ground; 1 

 never saw another example in that place. In .January 1897 I took a specimen at 

 Cachabi, N. W. Ecuador. In February of the same year I took a third example of the 

 species, ou the road from Cachabi to Paramba; in this the red is confined to rather less 

 than the apical half of the elytra, but it covers the whole of those parts of the costae 

 contained within that space. In both the Ecuadorian specimens the thorax is black,
