In the present paper we have treated only the true ground-beetles. 
The 16 Say species of tiger beetles (subfam. Cicindelinae) are omitted 
and also 12 species described from Mexico. The remaining specific 
names given by Say among the Carabidae are 147 in number. Leng 
(1920) gives the same figure, but two of his names (Calosoma in- 
distinctum , Harpalus iricolor), listed as synonyms, are nomina nuda. 
On the other hand, Calathus gregarius, in Leng, was attributed to 
Dejean instead of to Say, and Harpalus similis ( Anisotarsus s.) 
was omitted. 
Of the two authors of the present paper, R. Freitag is responsible 
for the 5 species belonging to genus (or subgenus) Evarthrus among 
the Pterostichini, whereas C. H. Lindroth studied the remaining 
species with kind help, in some cases, from the following experts, 
who selected neotypes among their specialities: 
Prof. R. T. Allen, University of Arkansas, Fayetteville, Ark., 
Loxandrus rectus. 
Mr. T. L. Erwin, University of Alberta, Edmonta, Alta., Brach- 
inus cyanipennis and B. stygicornis. 
Mr. T. F. Hlavac, Harvard University, Cambridge, Massachu- 
setts, Clivina pallida. 
Say’s descriptions were usually good, sometimes excellent for his 
time. Nevertheless, many of them, notably of course in critical genera, 
cannot be reliably interpreted. Unfortunately, Say’s private collection 
was entirely destroyed after his death (Leconte 1859a, p. VI; Ord 
1 859, P- XIX, footnote), and a comparison with authentic Say 
specimens is therefore excluded (but see below). For the correctness 
of the present applications of his names, we are indebted primarily to 
John L. Leconte who, in 1859, edited “The Complete Writings of 
Thomas Say,” with comments as to the right interpretation and 
taxonomic position of most Say species of Coleoptera,. The Leconte 
Collection, in the Museum of Comparative Zoology (MCZ), Cam- 
bridge, Mass., provides a complete picture of how the Say species 
were interpreted by him. 
In order to stabilize future use of specific names given by Say, it 
is highly desirable to designate type specimens. The aim of the present 
paper is to do so, as far as ground-beetles are concerned. It might 
seem, considering the total destruction of the Say Collection (see 
above), that a selection of neotypes would be the only solution. 
However, it so happened that Say distributed specimens from his 
own collection to at least one of his contemporaries abroad, Count
