art.21. DRAGONFLIES OF BURMA AND LOWER SIAM—LAIDLAW. 13 
The precise range of the species is undetermined; it is chiefly found 
in the Moluccas and Papua. I have not been able to examine speci- 
mens; but Ris regards it as a monomorphic species. 
Synonym.—Anax panybeus Hagen. 
ANAX FUMOSUS Hagen. 
With well-defined T-mark on frons. Thorax with black lines on 
the sutures. Coloring of abdomen richer than in the two preceding 
species, bluish-green spots on a black ground. Markings on segments 
3-7 consist of paired apical and basal spots on each segment; on 
segments 4—6 the basal spots are transversely divided by a narrow 
black line into two. 
Length of abdomen of male 48 mm., upper anal appendages, black 
in color, 6.2mm. Third segment of abdomen 9 mm. long. Hinder 
wing and pterostigma 0.48 and 4 mm. in length, respectively. 
I have seen specimens from the Himalayas (Coll. Indian Museum) 
and Japan (Brit. Mus.). The typical race is from Ternate. Doctor 
Ris tells me he possesses examples presumably of a form of this 
species from Java. He believes it to be a variable species probably 
with local races. The measurements given above are from an exam- 
ple from Darjiling. The precise range of the species is not deter- 
mined. 
Apparently the form described by Martin in the Monograph under 
the name Anaz bacchus is really an example of fumosus. The true 
Anazx bacchus Hagen is a synonym of Anaz parthenope de Selys.® 
LIST OF ORIENTAL SPECIES OF GENUS ANAX. 
1. Anax (Hemianaz) ephippiger Burmeister: India, Mediterranean countries. 
2. Anax parthenope de Selys: India as far south as Mysore; Palaearctic. 
3. Anax immaculifrons Rambus: Damascus, India to Hongkong. 
4. Anax guttatus Rambur: Seychelle Islands to Papua and Samoa. 
5. Anax gibbosulus Rambur: New Guinea, Moluccas. 
6. Anax fumosus Hagen: North India, Japan, Celebes, Ternata. 
Genus ANACIAESCHNA de Selys. ® 
Three species are included in this genus which has a wide range in 
the old-world tropics. Of these Anaciaeschna jaspidea Burmeister 
extends from India and Burma through Malaya and New Guinea to 
the Pacific. It has been recorded from Tahiti. The closely allied 
5A short account of the Aeschnine dragonflies of the Indian Empire has recently appeared in the 
Records of the Indian Museum, (vol. 22, pt. 2, no. 11). 
This was written by myself before I had undertaken the present paper. In that account I have 
described briefly three series of specimens belonging to the genus Anaz, as ‘‘series A, B,C” of Anar 
guttaius. I now regard “series A’’ as examples of the true guttatus of Rambur; ‘series C’’ as belonging 
to fumosus Hagen; whilst the single specimens which constituted ‘‘series B ”’ I take to be either a form of 
fumosus, or possibly a hybrid guttatus and fumosus. 
6 While this paper was in press Fraser (Journ. Bombay Nat. Hist. Soc., 1922, vol. 28, p. 699) has 
described an interesting and distinct new species from Southern Peninsular India under the name 
A. donaldi.
