Hab. Nort America ! 2, Illinois (coll. Dist.), Texas (Mus. Vind. Ces.), California 1 *. 
—MeExico 12, San Luis Potosi (Dr. Palmer). 
A Mexican specimen is here figured. The species varies in having either a sinuated 
red fascia, or three red spots near the middle of the pronotum, and also in having the 
membrane either unicolorous or spotted with white. I agree with Prof. Uhler in 
considering this but another form of JL. turcicus; but as he places it as distinct, I 
again follow him and Stal. The totally black clavus is one of the best distinctive 
characters.

Hab. Norra America ???,—Mextico '. 
The type of this insect is no longer contained in the British Museum. Mr. Dallas gave the habitat Mexico 
for his type; and Walker has placed a North-American specimen (not L. analis) in its place, which he erro- 
neously recorded as above”. Mr. Butler informs me that many types were thus lost or misplaced by Walker. 
It would from the description appear to be very closely allied to L. ruficeps, Stal.
