COLEOPTERA 597 



articulo sexto minus elongate, sed praecedente evidenter majore. Pronotum opacum, 

 lateribus dense pallide-tomentosis. Elytra tomento pallido, plus minus lineas longitudi- 

 nales formante, variegata, leviter striata, stria secunda cum quinta, vel cum stria quadam 

 exteriore, confluente, et striam tertiam et quartam aut complures alias includente. 

 Long. 3 mm. 



Structurally this species is closely allied to X. beddardi and others. It is very 

 variable and difficult to describe. The male, as is often the case in the genus, is 

 generally a narrower and more elongate insect than the female though sometimes the 

 sexes closely resemble one another. The pale tomentum of the elytra is nearly always 

 .so disposed as to form a number of linear markings ; in a few males the surface is so 

 generally covered with pale tomentum or pubescence as to almost obliterate this 

 character. In various parts of the elytra the tomentum is set in different directions, 

 giving it a microscopically roughened appearance, and in some specimens, in consequence 

 of this, there appear to be two well-marked bare red spots near the middle of the wing- 

 cases. This bareness is not real, and many e.xamples show no trace of the red spots. 

 Sometimes there is a good deal of red suffusion of the elytra otherwise. In many 

 specimens a conspicuous patch of pale tomentum is placed on each side of the elytra 

 about the middle of their length. The pronotum is often bordered with red and 

 sometimes entirely red. The legs are variable in colour in the female but in the male 

 are yellow or clear red. The variability seems to affect the species on each island, and 

 even if there is a tendency for the examples from one to vary in a special direction 

 (which is probably true to some extent) yet individuals from each that match each other 

 very well can be picked out without difficulty.

I have seen only two males of this species and assign also a single female to it. 

 It belongs to the X. oai/atus group, not having the distinct anterior margin of the 

 pronotum of X. nuptiis, some smaller examples of which it greatly resembles, the elytra 

 showing two more distinct red spots on the dorsum towards the middle. The pro-
