HYMENOPTERA — SCOLIIDZ. DANII 
the males of Myrmecodes in the subfamily Sapygides, under that of 
Thynnus. Scotzena also has apterous females.* Mr. Curtis has sug- 
gested a relation between Sapyga and some of the parasitic Andrenide ; 
and Latreille has noticed the relation between that genus and the flat- 
winged wasp genus Ceramius. It appears to me, however, that a 
much nearer affinity exists between Tiphia, Meria, &c., and some of 
the Proctotrupide, especially Epyris, Bethylus, &c. Dr. Klug’s genus 
Pristocera (Bethylus depressus Fad.) is especially interesting in re- 
spect to this affinity. 
The typical genus Scolia F. is distinguished by the labium being 
composed of three linear divisions ( fig. 84. 8. front of head of Scolia). It 
is of great extent, and comprises many very large species, inhabiting 
the hottest regions of the globe. M. L. Dufour, who has published an 
elaborate anatomical essay upon the largest European species, S. hor- 
torum (Journal de Physique, September, 1818), states that they abound 
in the very hottest situations, and that they are particularly fond 
of revelling in strong-scented flowers, such as rue, &c. A correspond- 
ent of the Entomological Magazine (vol. iii. p. 463.) states that Scolia 
2-cincta Fab. makes its burrows in sand-banks, to the depth of 
eighteen inches, with a very wide mouth ; in digging into one which 
a female had entered, he found a large locust, L. lineola, which is 
probably its prey. It flies without any hum: the male is taken singly 
on flowers; but the males of S. interrupta and 4-punctata, which are 
extremely sluggish, are found crowding on the ears of grass near the 
sea-side, in societies of twenty or thirty, where they pass the night, and 
make no attempt to escape. The males of S. 6-cincta (?) are found 
in similar localities; but the male of another species was solitary, and 
generally found on the flowers of the bramble, and was tolerably 
active. The males have the extremity of the abdomen tridentate 
(fig. 84. 9.) 
The species of this and the allied genera have been investigated 
by Dr. Klug, in Weber and Mohr’s Beitrage, above referred to. Ac- 
cording to St. Fargeau (Ene. Meth. tom.x.), the females of Tiphia 
( fig. 84.1. T. femorata 2 ; fig.84. 2. labrum; fig. 84. 3. mandible ; 
* The females of the genus Myzine Latr. have not yet been discovered; but from 
analogy with Tengyra, I have little hesitation in considering that they are apterous, 
as suggested by Van der Linden and Guérin, the former considering it probable that 
the Mutilla diadema Fab. may be the female of Myzine cylindrica. Plesia, 
which has been regarded as the female of Myzine, is more nearly related to 
Tiphia,
