COLEOPTERA 253 



(22) Mccyclothoi-ax sobrinns, sp. nov. 



Nigricans, supra fusco-subaeneus, parum nitidus. antennarum basi, palpis pedibusque 

 testaceis, femoribus fusco-plagiatis ; prothorace fortiter transverse ; elytris foveolis quatuor 

 magnis, et versus apicem utrinque impressis, subtiliter striatis, striis impunctatis, externis 

 obsolescentibus. Long. 6 — 6^ mm. 



Antennae elongate ; head broad. Thorax very strongly transverse, the sides but 

 little rounded, only moderately narrowed behind, the hind angles slightly prominent 

 so as to be minutely rectangular ; the surface with a dull silky lustre, the transverse 

 impression and the median channel distinct, the base but little punctate, the lateral 

 margin moderate. Elytra rather long, not much rounded at the shoulders, of a peculiar 

 pale-reddish, obscure colour with slight metallic reflections, the foveoles very large and 

 deep; the ante-apical impression very strongly marked. 



In the male the femora are thicker, the front femora beinij verv thick; the front 

 tarsi are more perceptibly dilated than they are in most of the other species. 



The four examples obtained of this remarkable species are rather immature and in 

 bad condition. It is doubtless distinct from J/, vtulfipunctatiis, the elytral foveoles not 

 being laterally duplicate. One individual has a supernumerary foveole on the right 

 elytron placed some distance in front of the anterior foveole. 



Hab. JNIaui. Haleakala, 5000 ft., in March and April 1894 (Perkins).

This species is easily recognised. It is of rather large size, and depressed form, 

 with short broad head, strongly transverse thorax, which is greatly rounded at the sides 

 and much narrowed behind, and each elytron has six abbreviated series of coarse 

 punctures. It is extremely variable, and I have noticed several curious aberrations of 

 sculpture and colour. 



It appears to be one of the commonest Carabids on Haleakala; Mr Perkins has 

 fifteen records of it from there, and it occurs from 4000 to 10,000 ft. It would be very 

 remarkable if it should also occur on the island of Hawaii. Mr Perkins has a specimen 

 labelled " Kilauea, Hawaii, without date." Thus considerable doubt attaches to this 

 individual. Curiously the species is also recorded from Hawaii in the papers by 

 Mr Blackburn and myself, Tr. Dublin Soc. (2) iii. 188=^ op. 214 and 276. I can, 

 however, find no direct record of its occurrence th _, oy Mr Blackburn, and I think 

 this is therefore probably an error, arising maybe from a hasty determination of 

 M. pele, the Hawaiian ally of M. inoiitivag..^. Under these circumstances I shall 

 consider J/, montivagus as a species peculiar to the island of Maui until satisfactory 

 evidence of its occurrence on Hawaii is forthcoming:.
