112 Mr. F. Walker on some new species of Chalcidites. 
fourth very minute; fifth and following joints long, linear, slightly 
decreasing in length until the tenth ; club linear, conical at the tip, 
much longer than the tenth joint : thorax nearly oval, very convex : 
prothorax rather large, transverse, narrower in front : scutum of the 
mesothorax large, transverse, having the scales on its surface dis- 
posed in minute transverse undulations; sutures of the parapsides 
distinct, slightly approaching each other; scutellum truncate-coni- 
cal, having a very narrow suture at the base: metathorax convex, 
prominent, decumbent: podeon not more than one-sixth of the 
length of the abdomen : abdomen nearly conieal, smooth, shining, 
slightly convex, narrower and much shorter than the thorax; meta- 
podeon covering more than half the dorsum, slightly concave at the 
base ; octoon and all the following segments very short : wings ample ; 
humerus less than half the length of the wing; ulna scarcely half the 
length of the humerus ; radius much longer than the ulna; cubitus 
about one-half of the length of the ulna; stigma very large, forming 
an irregular cone whose tip points toward the radius. 
Found by Dr. Greville near Edinburgh. It is nearly allied to L. 
elegans.

Female.—Body convex : head and thorax finely squameous : head 
large, transverse, a little broader than the thorax: antenne short, 
compact, subclavate, rather shorter than the thorax ; first joint long, 
linear ; second cyathiform ; third and fourth very minute; fifth and 
following joints linear, successively decreasing in length until the 
tenth, which is as broad as long; club linear, conical at the tip, 
much more than twice the length of the tenth joint: thorax very 
convex : prothorax moderate, transverse ; fore corners rounded : scu- 
tum of the mesothorax large, longer than broad ; sutures of the par- 
apsides very distinct, approaching each other; axille large, trian- 
gular, not conniving; scutellum truncate-conical, very prominent, 
not impressed in front, but having a transverse channel before the 
tip : metathorax large, obconic, decumbent : podeon short, stout, not 
more than one-sixth of the abdomen in length: abdomen short-oval, 
shining, very finely squameous, deep, very convex, much shorter and 
a little narrower than the thorax ; metapodeon conical, quite smooth, 
channeled and abruptly decumbent towards the fore border, occu- 
pying a little less than one-third of the dorsum; octoon more than 
half the length of the metapodeon ; ennaton shorter than the octoon ; 
decaton as long as the ennaton ; protelum short ; paratelum and te- 
lum very short: wings ample; humerus much less than half the 
length of the wing; ulna rather less than half the length of the hu- 
merus ; radius very much longer than the ulna; cubitus stout, much 
shorter than the ulna; stigma large, pyriform, emitting a short 
branch towards the radius.
