In the following year Zeller published figures of this 
species, but without any text beyond description, in Bull. 
Soc. Nat. Moscou. Figure 17 shows the whole insect, 
but it is to be noted that the second segment is here 
shown as cleft from about whereas figure 20 (which 
gives a more enlarged view of two wings) shows this 
cleft from h only in accordance with the description. 
Figures IS and 19 show the raid- and hind-leg. 
The following is a redescription of one of Zeller’s original 
specimens of D. tengstroemi, now preserved in Lord Wal- 
singham’s collection. It is labelled “ Java, Tengstr.” and 
also “ Type 2/2 ” :—

ginous ; second joint very slightly dilated at apex, where it is banded 
with dark-ferruginous ; third joint slightly over half length of 
second, aexuninate, broadly banded with dark-ferruginous at base 
and apex. Antennae dark-ferruginous, dotted with whitish above. 
Head light-ferruginous, top of crown with long anteriorly-erected 
scales. Thorax light-ferruginous ; pectus marked with whitish.

spots on second segment, and of a narrow transverse white band 
along posterior edge of third segment; ventral surface white, mottled

lightly suffused with ferruginous except on costa at i length of seg¬ 
ment, cut at about | by a nearly obsolete inwardly-oblique whitish 
line; second segment lightly suffused with ferruginous, first subseg¬ 
ment with a minute whitish dot near base. Cilia on costa light- 
ferruginous, slightly darker on base of first segment, on first segment 
black at f as a slight bar, with slight blackish admixture at | and |;
