In 1915, at the time the American species of Conocephalus 
were revised, no material of the present species was available 
for study. 
The type series, belonging to the collection of the Leland 
Stanford Jr. University, is now before us. The specimens from 
James Island were taken on April 22, 1899, those from Inde- 
fatigable Island on May 1, 1899. We here select a male from 
James Island as type, a female, bearing the same data, as allo- 
type, of this interesting species. 
The species is found to belong to ithe subgenus Xiphidion 
Serville and shows close agreement with C. nemoralis (Scud- 
der), a species peculiar to the central-eastern interior of the 
United States. 
The males in general appearance agree rather closely with 
males of nemoralis**, showing in the cerci, however, a condi- 
tion in some respects intermediate between the types developed 
in nemoralis and C. occidentalis (Morse), the latter a species 
21 The coloration of the present specimens can not be determined, except that the ver- 
tex and dorsum of the pronotum are marked with a very broad band of dark brown. 
McNeill gives green as the general coloration of the species.
