‘(Hemigaster) Syrites jacobsoni (Szépligeti).— 
Notes Leyden Mus. 29 (1908) 245, male. 
This Javanese species is apparently so closely allied to S. 
metathoracica (Ashmead) that a male of the latter species com- 
pared with Szépligeti’s description differs only in having the 
thorax and propodeum entirely black and the nervellus distinct- 
ly antefurcal. 
(Hemiteles) Syrites bidentatus (Szépligeti). 
Notes Leyden Mus. 29 (1908) 252, female. 
This species, also from Java, is very likely the female of S. 
jacobsoni (Szépligeti). Szépligeti is the only one who has 
mentioned the lateral angulations on the third tergite in the 
female, but the analogy between these and the spines on the male 
escaped him. 
(Ischnocerus?) Syrites cancellatus (Brullé). 
Hist. Nat. Ins., Hym. 14 (1846) 262, female. 
In the preceding key I have separated S. bidentatus (Szé- 
pligeti) from this and two other species on account of the clouded 
base of the wing. As a matter of fact Brullé makes no mention 
of this, describing the wing simply as having an incomplete 
brown band; and I suspect that Szépligeti has redescribed 
Brullé’s, species, especially as they are from the same island. 
Syrites acanthogaster Tosquinet. 
Mem. Soc. Ent. Belg. 10 (1908) 118, male. 
This Sumatran species seems to be distinct from the rest in 
having only the first tergite red, the mandibles black, and the 
propodeal spiracles large and slightly oval; it may be that I 
am wrong in referring the other species to Syrites, but in all 
other respects Tosquinet’s description accords so well with the 
male of S. metathoracica (Ashmead) that it seems impossible 
that they are not congeneric. 
(Camptolynx) Syrites ? fuscipennis (Cameron). 
Berl. ent. Zeit. 55 (1910) 253, male. 
This and the following species, both from Ceylon, are the 
basis of Cameron’s genus. Because of the stated position of 
the spines on the fourth tergite instead of the third they are, 
as stated above, doubtfully referred to Syrites, and Cameron’s 
genus is doubtfully synonymized with Syrites.
