to the same species specimen 17-12. Both obverse and reverse of 
17-11 are in the Museum, but only the badly preserved obverse of 
specimen 17-12 could be found. Fortunately, Dr. Carpenter put at 
my disposal a good photograph of the reverse, which he made in 
1938, so that a drawing of specimen 17-12 could be worked out very 
satisfactorily, also. The following account is based on the type 
specimen. 
Wings slightly unequal, the hind pair being a little longer. Wing 
membrane very thin. Dark stripes following costa, subcosta, apical 
margin, and supporting structures. Cuticular thickening V-shaped. 
Dark band extending from cuticular thickening obliquely to R ; a 
cross vein, rs-ma, running obliquely in the opposite direction. Fore 
wing: length 33 mm, width 9.3 mm. Anterior and posterior mar- 
gins almost parallel for about two-thirds of wing length. Apical 
part narrowed, apex pointed, directed posteriorly. Rs with about 
6-7 branches; MA pectinate, with 2-3 branches; CuP simple. Anal 
area with about ten branches, sometimes forked. Cross veins few, 
almost regular, arranged in two rows parallel with the posterior 
margin. Hind wing: length 34 mm, width 12 mm. 
Body structures: Head length 1.5 mm, width 1.4 mm. Eyes of 
average size, projecting. Clypeus almost rounded. Antennae about 
12 mm long, composed of equal, cylindrical segments. Prothorax 
half as long as mesothorax, almost square; prothoracic lobe: length 
4.7 mm, width 4 mm, margin slightly undulated, veins about 1 1 in 
number, cross veins not numerous. Mesothorax about 1.4 times 
longer than metathorax. Fore legs very short, length of femur about 
3 mm. 
In his description (1893), Brongniart mentions the V-shaped 
cuticular thickenings and suggests the possibility that they were 
stridulatory organs, which seems probably incorrect. 
Homaloneura elegans is related to bonnieri by its thin wing mem- 
brane, similar color pattern and wing venation. It differs in its 
smaller size, shape of wings, and the much less dense cross venation 
of the prothoracic lobes.
