THE DISCOVERY OF ECLIMUS HARRISI IN THE WHITE 
MOUNTAINS, N. H. 
By Cuarues W. JOHNSON, 
Boston Society of Natural History. 
This interesting species has long been known only by the type, 
a male, in the Harris collection, in the Boston Society of Natural 
History. It bears the label, ““H. Gray,” without date or locality. 
It was described by Osten Sacken as E’pibates harrisi in his Western 
Diptera (Bull. U. S. Geol. Survey, Vol. 3, p. 273, 1877). In the 
note following the description he says: “It is probably from the 
Northern United States as are nearly all the specimens in the 
collection.”” On page 271 in the table of species it is referred 
doubtfully to the “Atlantic States (?),”” but in the table of con- 
tents where all the species are arranged systematically with local- 
ities, ““ Massachusetts” is given without a question. I am unable 
to find any authority for this and doubt if Osten Sacken made the 
table of contents. 
During the meeting of the New England Federation of Natural 
History Societies at the Glen House the first week in July, frequent 
collecting trips were made to various parts of the mountains. On 
July 8, I captured a male of Eclimus harrisi on the flowers of the 
blackberry on the Mount Washington Road near the Raymond 
trail, just below the two-mile post, at an elevation of about 2,600 
feet. This resembles the type in every respect except that its 
length is 12 mm. while the type measures 14mm. A female of 
this species wa; taken by Mr. C. A. Frost, July 6, along the 
railway, above Base Station. 
A REVIEW OF OUR SPECIES OF TRIGONOMETOPUS 
(DIPTERA; LAUXANIID/®). 
By FreEepERIcK KNAB, 
Bureau of Entomology, Washington, D. C. 
The Lauxaniid genus Trigonometopus is easily recognizable by 
the peculiar shape of the elongate head, triangular in profile, with 
the frons horizontal and the face strongly receding, the antenne 
nserted at the apex of the triangle. Four species have been
