DIPTERA 



31 



Hab. Lanai, two males from the Koele Mts. (over 2000 ft.), in July 1S94. 



A female from Kauai, 2 — 3000 ft., i. and 11. 1897, may belong to this species. It 

 only differs from the males here described as follows : face duller, the tomentum hardly 

 silvery, cheeks more distinctly hairy, abdomen less bristly, with more or less distinct 

 paired spots on all the segments, tarsi somewhat darker, only yellowish towards the base 

 of the metatarsus, intermediate and hind femora much less bristly, wings only very 

 slightly tinged. 



Ltspe nietatarsalis Thorns. (Eugen. Resa. Dipt., p. 562), from Honolulu, must be 

 closely allied to, and may be identical with, this species, but his description is too vague 

 to render this a matter of certainty. For the sake of comparison it is here reproduced : 



" Griseo-olivacea, palpis albido-testaceis, antennis nigris, tibiis metatarsoque obscure 

 testaceis ; alls subfumatis ; abdomine vitta media dorsali, lineam mediam angustam 

 albidam includente, fusco-nigra. ?. Long. 5 mill. 



" Patri.-\. Honolulu. 



" Praecedenti [Z. vittipciuiis Thoms.] simillima, lacie griseo-cervina ; thorace baud 

 vittato ; halteribus flavis ; alis obscuris, subfumatis ; abdomine pube griseo-albida, vitta 

 media dorsali fusco-nigra, lineam angustam albidam includente, lateribus punctis nigris, 

 setas et pilos longiores gerentibus ; tarsis basi obscure testaceis bene distincta." 



(2) Lispc cupreigeiia, sp. nov. 



^. Long. Corp. 4^ mm. ; al. 4 mm. Very like the preceding species, but smaller, 

 the face cinereous, the cheeks with a peculiar coppery tinge, abdomen with paired spots 

 on the three last segments, tibiae and apices of femora lighter yellow, wings quite clear, 

 tegulae whitish without dark margins. 



H.\B. Oahu, one male, Waialua, Koolau range, coast, March 1892. 



Lispe, spp. 



Two other species of this genus may perhaps be represented in the collection 

 obtained by Mr Perkins. One of these, of which there is a single specimen from 

 Kilauea, Hawaii (September 1895) and another from Molokai Mts. (4500 ft., September 

 1893) is a species about the size ot L. argenteifacies and similar to it in many respects, 

 but the face is covered with yellow, almost golden, tomentum, the cheeks are more hairy 

 and the fore tarsi are entirely black. The specimens are too badly preserved to be 

 described in detail. The other species is represented by four specimens in poor con- 

 dition from Koholuamano, Kauai (April 1895) and one equally bad from Kona, Hawaii, 

 4000 ft. (August 1892). These are about the size of the second species described 

 above, with the face greyish, the fore tarsi reddish-yellow at the base, and the wings 

 slightly tinged.
