COLEOPTERA 591 



X. protcus var. mattrus nov. 



Elytra nigro- vel fusco-tomentosa, apicibus extremis nonnunquam cinerascentibus. 



A dark form, the elytra nearly uniformly dark, the tomentum generally with 

 a ferruginous or golden reflection in certain aspects. About one example in 60 appears 

 to belong to this variety. 



X. protcits var. apicalis nov. 



Elytra supra pallide tomentosa, lateribus fasciaque anteapicali, saepe etiam basi 

 niofricantibus. 



In this form, which is numerous, the base of the elytra (usually more widely at the 

 shoulders), the sides, except a space behind the shoulders, and a transverse mark or 

 band near the apex, are black. Rarely this subapical fascia alone is present. 



X. protciis var. dorsalis nov. 



Elytra plus minus pallide tomentosa, post media macula magna trans suturam 

 posita ornata, fasciaque subapicali saepe interrupta. 



This beautiful variety is not abundant. Of five hundred specimens counted, only 

 one in fifty belongs to it. I have seen one very good intermediate form, in which the 

 pale tomentum has not been entirely eliminated from the dorsal spot. 



X. proteus var. hastatits nov. 



Elytra nigro- vel fusco-tomentosa, ante media macula trans suturam posita, sub- 

 triangulari, pallide tomentosa ornata. 



A very remarkable variation, the pale pubescent spot on the suture being sub- 

 triangular (the apex of the triangle in front) and a little produced backwards along 

 the suture. 



Only three examples in about 600 examined were of this variety. 



X. protcjis is apparently found on all the islands, but unless X. nuptus be 

 considered a mere variety, it was only found abundantly on Hawaii. The var. apicalis 

 has been taken on Kauai in company with X. nuptiis and I have seen one var. dorsalis 

 from Oahu, taken with nearly X.^"^\<i?i\. proteus. 



X. inesochloriis from Molokai reminds one greatly of the var. hastatiis, but the 

 pale spot is differently shaped, and occupies a different position on the elytra and it is 

 I suspect nearer to X. niiptits than to the var. hastatits of protcus. After the remova' 

 of A', nuptus, X. iiicsoclilorus and X. miniiis all Hawaiian Anobiids of large size, with 

 very densely tomentose head and sides of the pronotum, with the anterior margin of
