IIKI'KIHTION TO POINT IIAKKOW, ALASKA. 135 



No. 11', taken July 11, ISSi', near tin- house, is L'roccrus Jlaricorn in Kabr. (family I'rorrii 

 ;i rather small specimen. This is an insect rather widely distributed, and its larva, as is the habit 

 of the, genus, doubtless either fed in UK; stem or trunk of some shrub or tree growing at I'oint 

 Barrow, or may have issued from timber taken to the I'oint for building purposes.* 



No. !">, taken along the dryer edge of the tundra, i.s again an Anthomyid. small, but allied to 

 No. >S, but under the same number there is a, single specimen of another Diptcrou belonging to the 

 genus Cordyluru, and, so far us I Lave ascertained, mulescribed but closely related to C. yilvipes. 

 It belongs to the same family with Scatophaga, and, without doubt, lias similar habits. There i.s 

 also under this number a single, very much damaged, specimen of a Neuropterous insect belonging 

 to the family Phryganida 1 or caddis-Hies. Ho far as the specimen permits an opinion, it comes near 

 Oliyoplettritm moroxum McLachlan. 



No. 14 contains two different species of Bumble-bees, the one Bombits moderatm Cresson, tho 

 other the common boreal form of B. sylvicola Kirby. 



No. 15, found on the shore of the lagoon, is another specimen of the Tipulid genus Ctenopliora 

 and without much question the female of one of those of No. 4. 



No. 10. I find no insect with this number. 



tNo. 17. A boreal Arctian ( ); also common to Europe and America. 



No. 18, caught near the house, is the well-known gad-fly (OSdemagena tarandi Linn.) of tho 

 reindeer ( Ctrvux tarandim var. arctk-H/t), which suffer much from the larva? making their way through 

 the skin. 



Of the alcoholic material, No. 649, found in the stomach of a bird (CenlropJtancs lapponicm), 

 belongs to the genus Chrysomela (family Chrysomelidce, or leaf-beetles), and appears to bo referable 

 to Ch. montivagans Lo Conte. Of this particular group of Chrysomela (Chrysomela sens, sir.}, 

 characterized by the thickened thoracic margin, only a few species are known to occur in North 

 America, in the majority of which the specific characters are very feebly expressed, the number 

 of species thus becoming more or less opiuiouative. Whether or not the only specimen from Point 

 Barrow is correctly referred to the above species must be left undecided until more complete 

 material from different localities can be compared. Le Coute described montivagans from the high 

 alpine region of Central Colorado, and the typical specimens are much larger and more brilliantly 

 colored than that from Point Barrow. 



Most of the species are quite interesting, as is generally the case with species collected in 

 such regions, where proper notes are made in connection with them. The misfortune is, however, 

 that most of the material is too poor for proper specific identification or description. It is for this 

 reason that I do not care to accompany this report with descriptions of the new species, though I 

 may send in descriptions of some of them before the report is published if I can find time to make 

 the necessary critical comparisons. It is preferable, however, to leave them for the present unde- 

 scribed until such time as some specialist shall work up the particular families or groups to which 

 they belong. There is little gain to entomology in describing such fragmentary material, and it 

 should not be done except where absolutely required. 



'The latter is probably tlio case, as there are no trees or shrubs large enough to maintain the insect growing at 

 Point Barrow. J. M. 



tTUis insect, though perfect when tnrued in, was accidentally destroyed iu tlio laboratory at the Agricultural Do- 

 partuient. J. M.
