OF INSULINDE, 97 
No doubt it also occurs in Dutch Borneo, as the fauna 
of that island is nearly generally distributed on it. 
Mantispa grandis Guérin. 
Mantispa grandis Guérin, in Duperrey’s Voyage Coquille, Ins. II, texte 11, 
p. 196, t. 10, f. 4 (1832). Amboina. — Rambur, Hist. Névropt. p. 433, 
n°. 4 (1842). 
Mantispa guerini Westwood, Trans. Ent. Soc. Lond. (2) I, p. 255, n°. 25 
(1852). — Walker, Cat. Brit. Mus. Neur. p. 220, n°. 25 (1853). 
This species, which is only known to me by the description 
and figure, is nearest related to simulatrix from Borneo 
and strenua from Java, and forms probably with them and 
some other australian species a distinct genus. 
Body black. Head broad, black, with white eyes. Pro- 
thorax black, rather short and thick, with many deep sulci. 
Antennae rather long, rufous brown. Meso- and metathorax 
black, broader than the prothorax. Abdomen as long as 
the thorax, narrower at the base, black. Legs blackish 
brown and of the usual form, the median and posterior pair 
with brown tibiae and tarsi. 
Wings narrow and very elongate, hyaline in the middle, 
broadly bordered with yellowish. Pterostigma and nervature 
also yellowish. Tips with an indistinct transparent brown 
spot. Costalveins in the forewing about ten in number. 
The following measurements are taken from the figure, 
which seems to be a little enlarged, as Guérin gives 20 mm. 
for the body and 49 mm. for the wing-expanse. 
Body 23 mm., forew. 26 mm., hindw. 22 mm., ant. 8 mm. 
Abd. 9 mm, gr. br. 6 mm, gr. br. 5 mm. 
Habitat: Amboina. 
Westwood is wrong when changing the name grandis 
in guerini, as there are three M. grandis for different 
species, and, independant from another given by Guérin, 
Erichson and Burmeister, Guérin’s name being the oldest, 
the others therefore want to be changed. 
The Sialidae, which also have been placed in the Plani- 
pennia, have been treated by me in the volumes XXVI
