446 TIPCTJD.E. 



subcontiguous beneath. Proboscis short, stout ; palpi compara- 

 tively short, the middle joints rather stouter. Antennae generally 

 rather short,* of sixteen joints; the 1st scapal joint varies in length 

 but is nearly always wider at the tip ; the lind is considerably 

 enlarged, much the widest of all, rounded, subcvlindrical or ovate, 

 occasionally of irregular shape ; 1st joint of the flagellum often 

 onion-shaped, and often much larger than the remaining flagellar 

 joints, which are oval, more or less, becoming considerably elon- 

 gated towards the tip of the antenna, the whole flagellum closely 

 pubescent, each joint bearing a vertical of long hairs. Thorax 

 somewhat high and convex, produced forwards conically into a 

 short blunt neck, which is inconspicuous in some species. Two 

 well-separated rows of dorso-central stiff hairs, which, beyond the 

 suture, generally diverge towards the posterior corners of the 

 dorsum.'t Thoracic suture distinct, and the post-sutural depres- 

 sion rather well marked. Abdomen linear, of moderate size, often 

 transparent, when the internal organs can be rather easily seen. 

 Genitalia of male consisting of a large fleshy basal joint which is 

 usually ovate or subcylindrical, and to which is appended some- 

 times a single horny hook or bifid claw, sometimes a second joint, 

 much smaller, bearing a terminal hard piece of some kind. Dif- 

 ferent intermediate small organs appear to be present in some of 

 the species, but they are not easily examined in dried specimens. + 

 The ovipositor in the female differs in length considerably ; the 

 upper pair of valves long, slightly curved upwards, the lower pair 

 set further back at their base, generally much shorter, and straight, 

 both pairs enlarged, in some species to a considerable extent, at 

 the base ; two small hornv projections are placed at the base of 

 the upper pair of valves. Leys slender, of moderate length 

 or rather short, pubescent, often very conspicuously hairy ; the 

 middle pair generally shorter than the others ; tibiaa without 

 apical spurs, einpodia distinct, ungues smooth on the inner side ; 

 the last joint of the tarsus is said to project somewhat over the 

 ungues. Wings rather broad, tip roimded ; veins pubescent, 

 especially towards the apical half of the wing, but the hairs 

 much more conspicuous in some species than in others. Two 

 submarginal cells and four posterior cells, the discal cell open 

 or closed ; the veins mainly parallel on the outer side of the 

 wing ; the auxiliary vein ending beyond the middle of the wing, 



* Osten Sacken observes that some species have the antennas in the female 

 long enough to reach to the base oi' the abdomen, but there are no species with 

 such long antennae in the East. 



t The chaetotaxy (if such it can be called, when referring to stiff hairs 

 instead of bristles and spines) has not been observed closely as the above 

 description appears to apply to all the species, in a greater or less degree, of 

 this and its allied genera. 



J Osten Sacken figures one North American species (E. armata, Os. Sac.) 

 in which the large basal joint is terminated by three horny teeth, united at 

 thei bases. 



According to Osten Sacken ; but I have not searched for them myself.
