¥Ou, Iv]: Lhe Species of Amblychila. 219 
description and a figure from Dupont and Reiche, but calls it 4. 
cylindriformis of Say, though neither the description nor the 
figure agrees with it. I fear that the author of the ‘‘ Mono- 
graphie des Cicindelides '’ must have been influenced by reading 
the opinions of our two great coleopterists and copied the 
description and the figure of Dupont and Reiche without review. 
Look at the figure on plate 3, fig. 3 in Thomson’s Mono- 
graph and guess what induced the author to call it 4. 
cylindriformis Say. ‘The two species are abundantly distinct 
and I feel certain that such eminent men as Le Conte and Horn 
have not been shown the insect that furnished the figure illus- 
trated in Thomson’s Monograph. Dr. Horn recently wrote me 
that the French coleopterists considered my 4. Baroni as a small 
example of 4. Prcolominiz. I had already begun to be of that 
opinion, and after further consideration I must own that the 
‘French opinion is the correct one. I hold that there are two 
species, viz.: Amblychila cylindriformis Say* and Amblychila 
Picolominit Dupont Collection, Pl. 19 fig. 1 46 and Reiche + and 
that Amblychila Baroni Rivers is the male of 4. Picolominiz. 
It appears to be an impossibility for anyone to write a correct 
history of Amdlychi/a and formulate a reliable description, or at 
least one that will meet with the approval of the coleopterolog- 
ical fraternity. The description by Say is rather terse, there 
being an omission of the very coarse and distinct punctuation of 
the apex of the elytra. Reiche seems to have done some bad 
work also, for his /Picolominii is said to have these coarse 
puncturings on the apex of elytra, showing that he must have 
had both species under examination, for the examples from 
Arizona are impunctate at the apex of theelytra. Reiche says: 
“‘de gros points irregulizrement placés i la base et a U'extrimité des 
élytres.’’ ‘The third form, which I recently received from Peach 
Springs, Northwestern Arizona, and which I take to be Reiche’s 
Picolominit and the species named Sarvonz from Southern 
Arizona, both have elytral apices free from points or punctures. 
So that Dr. Horn and others must have some other reasons for
