crimson to violet, iridescent only in certain lights, impunctate at apex, 



strongly punctate anteriorly, the punctures brilliant crimson ; pimeriaiia 



smooth, uniform green, iridescent in certain lights, strongly punctate 



throughout, as in fidgida, the punctures being vivid violet towards apex, 



more brassy towards humerus. The apparent bluish colour oi pimeria?ia 



is probably due to the combination of green and violet, as there is not 



the slightest trace of blue to be seen under the microscope." 



The late M. L. Linell, in Proceedings of the National Museum, No. 

 1096, pages 726-7, describes Lachnosterna alpina from four male speci- 

 mens, taken near Alta, Utah. Last December Mr. Tom. Spalding gave 

 me two specimens of this insect, which he obtained by digging, at an 

 altitude of about 10,000 feet, on November 26th, near Alta. They were 

 male and female, and as the original description was made from males, 

 some notes and comparisons with the male may be of interest. 



Male: length, 17 mm.; width, 9 mm. Female: more robust ; length, 

 18 mm.; width, 10 mm. Antennal club a little more than half the length 

 of the stem. Punctuation of thorax not so dense as that of the male, but 

 punctures deeper. Punctuation of head dense and deep. Hairs on 

 metasternum not so long or numerous as in male. Pygidium sparsely 

 punctured, with punctures deeper than in male. Hind tarsi shorter and 

 more slender than those of the male. Penultimate segment of abdomen 

 strongly margined. The genital structure is very close to that of dtibia ; 

 the pubic process is almost identical with that of diibia^ except that it is 

 smaller, slightly flatter and the truncated tips slightly arcuate, with the 

 bristles at the tip and on front surface more numerous and not so long as 

 in dubia. The superior plates the same as in diibia.

 year 1905. Honolulu, April 3, 1906. 36 pages, two plates. 



The group of able and enthusiastic Entomologists now resident in 

 Honolulu have organized a Society and published their first year's 

 proceedings in pamphlet form. While the papers and discussions 

 naturally deal with local species, there is much in them of general 

 interest ; the most important article is Mr. Van Dine's " Notes on a 

 Comparative Anatomical Study of the Mouth-parts of Adult Saw-flies," 

 illustrated with two plates. We heartily wish abundant success and 

 continued prosperity to this new Society and its members,
