acute internal angle and a broad, black caruncle under the obtuse external 
angle.” (The italics are mine. R. A. M.) This description is in per- 
fect accord with my published figures. Figure 14 showing the lateral 
of the appendages, and figure 16 showing the dorsal view were less suc- 
cessfully reproduced than I had expected, and what was intended to indi- 
cate the caruncle may easily be taken for an accidental thickening or care- 
lessness in drawing; this is notably so in figure 16. Figure 14, however, 
shows the tubercle with sufficient distinctness. 
In view of the loss of the original type, and the thorough agreement of 
the Brooklyn Museum specimen with Needham’s description, and in con- 
formance with instituted taxonomic practice the writer designates the 
Brookljm Museum specimen as “Gomphus lentulus Needham, neotype 
by designation.” 
Though some small differences were listed in my paper, it must be re- 
membered that Needham had only a broken, patched, and presumably 
discolored specimen available for his original description. Except for a 
discoloration of the posterior segments of the abdomen the Brooklyn 
Museum specimen is otherwise completely matured, hence in good color- 
ation, which would account for the slight discrepancies as to color and 
markings. These, however, are none that exceed the limits of variation 
customary in Gomphus, and hence little significance is attached to the 
differences. It is the perfect agreement of the figured specimen and the 
original description of the appendages that seems to me as decisive in 
this question of identity. R. A. Muttkowski.]
