S. fruhstorferi Rothsch. (] 1 i) has the forewings hyaline, marked as in signata (lOi), with a dark 
transverse band near the base, adjoining an hyaline basal spot. Body black. Easy to distinguish by 3 purple 
bands on the 2 nd , 3 rd and 6 th segment of the black abdomen. In the ? the forewings are more profusely 
black. Discovered by Fhuhstorfer in the Manson Mountains (Tonkin). 
S. adjuncta Wkr. (lli). Frons golden-yellow, thorax marked with yellow, and the abdomen with 
rows of lateral golden-yellow spots. Forewing hyaline, from end of cell to the broadly black-brown apex a 
black streak, another between the medians. Not unsimilar to certain species of Ceryx of the formicina- Group, 
f. i. keiensis, with which it is generally found together. Ceram, Amboina, Key Islands. 
S. celebesa Wkr. (lli), a lovely species; forewing black-fuscous with hyaline spots in and below the 
cell, and before apex and outer margin. Most characteristic are the gorgeously crimson abdominal bands 
encircling segments 2, 3 and 4, and indicated on the other segments by lateral spots. Celebes. — ab. gracilis 
Rob. (= elvira Pag.) (Hi) has the hyaline spots longer and the red abdominal bands more numerous. The 
figured specimen came from Minahassa. — sulana Lathy from Sula-Mangoli and Sula-Besi differs from typical 
celebesa in having the abdominal rings interrupted on the back. 
S. kalidupensis Rothsch. (Ilk) is at once recognized by the vermillion hue of head and shoulders, 
collar and abdominal rings. The latter give it a resemblance to celebesa, but it is smaller and has the spots 
larger and more numerous, especially in the middle of the wing whence they almost reach the base. From 
Calidupa (Tukan-Besi near Celebes), where it was discovered by H. Kuehn. Our figure represents the type. 
S. henrici Rothsch. is black, with slight green metallic lustre. Collar and a spot on the last abdominal 
segment crimson. Anal tuft of c? brown. But few hyaline spots on forewing, one in the cell, and in cf 2 
other smaller ones between veins 3 and 4, and 4 and 5. Hindwings not spotted. Timorlaut, Dammer, Letti, 
Sermatta, Larat. 
S. era Sivinh. from the Khasia-Hills. Head and thorax orange, the latter striped with black; abdomen 
of cf with 7 golden-yellow rings. Wings golden-yellow, bordered with black, and marked with transparent 
spots. The terminal band dentate on the ribs. Hindwing with hyaline spot below rib 1, but without the 
dark discoidal spot found on the forewing. 
7. Genus: Syiiiplileboniis Hmps. 
This genus is easy to recognize by the large, oval, raised patch which extends on the forewing from behind 
the end of the cell to near the apex and which is even more clearly noticed on the under surface of the 
hindwings. This results in rendering the neuration abnormal, reducing the veins somewhat on the forewing, 
in as much as the median vein which follows its normal course as far as half the length of the cell, here 
suddenly turns in the direction of the apex of the wing until it reaches said patch the lower margin of which 
it follows; thus the cell is widest in the middle and tapers considerably towards the apex, as is also the 
case in Streptophlebia which the only known species resembles as to neuration, but from which it differs in 
the greater length of the hindwings and the completely different shape of the anal angle of the forewings. 
S. antipolo Setup. (9f), a pretty small sized species reminding us of certain Eressa. Forewing 
characterized by a black, oval discoidal spot, corresponding to the marks on the wings of Ichneumonidae and 
differing in its position from the hyaline spots of all other Sgntomidae.. Forewing with only 3 spots, a 
longitudinal one in the cell, a larger, wedge-shaped one below it, and a double spot between the medians. 
Hindwings transparent, costa, apex and apical half of outer margin black. Body black, only the forehead 
white and patagia yellow. From the Philippines. Figured from a cf in Semper’s Collection at Francfort o. M., 
taken on June 8 th near Manila. The antennae which in whasp-fashion are spirally curved, and the very long 
hindlegs, together with the characteristic mark on the wing render it beyond doubt that the living insect 
mimics an Ichneumonid. 
8. Genus: Paraceryx Beth..-Baker. 
This genus was based on a single species which was discovered some years ago in New-Guinea. 
As in nearly all Sgntornids, the tongue is strongly developed; antennae simple, the mid tibiae provided with 
one, hind tibiae with two pairs of spines. Rib 2 arises before the last quarter of the cell, 3 before and 4 
at the angle, 5 above it. 2 and 3 are downcurved towards the margin, 5 upwards, 7, 8, 9, 10 and 11 are 
stalked. On the hindwing the cell is lengthened, rib 2 arising before the middle, 3 before its apex and 5 at 
the angle, 7 and 8 with short stem. Inner margin projected so as to form a long flap. Nothing is known 
of the earlier stages.
