can be detected being a slight channel along the middle of the basal half; the outline 
of the front margin of the thorax at the sides is more sinuate, or, in other words, 
rudimentary ocular lobes are undoubtedly present. E. fallax is apparently a rare 
insect, as the collections received by our editors contain only a pair of the species, and 
there are two pairs of old specimens in my own collection; these were all named 
L. fallax—those in my own collection on the authority of Jekel—and they agree with 
the type of the species sent me by Dr. Aurivillius. |

This is another variable species, certain specimens of which resemble extremely 
some of the varieties of EL. mexicanus. E. nebulosus may, however, always be distin- 
guished from the commoner species by the following characters: the rostrum is 
shorter; the eyes are more convex; the head behind the eyes is subconstricted and 
the outline of the front of the thorax at the sides is very sinuate, so that a distinct, if 
rudimentary, ocular lobe is present. The rostrum in £. nebulosus is in each sex 
deeply impressed, and the sides of the depression are more abruptly raised, and 
converge less at the forehead. . nebulosus is apparently not a common insect, and 
nearly all of the fourteen specimens we have received of it are old examples from 
Sallé’s collection. The marks on the wing-cases—on which Boheman chiefly relied 
when discriminating E. nebulosus—are distinct in some examples only, being in others 
entirely absent. The size of the individual is on the average very much less than it is 
in L. mexicanus, but the largest examples considerably exceed the smaller specimens 
of the commoner species in stature. 
The example sent me as /. nebulosus from Schonherr’s collection is a small male of 
ff. mexicanus, but I anticipate that other specimens in the Schonherrian collection 
may prove to be the insect I now call E. nebulosus; if this, however, should not be 
the case the species will require a new name. .

E. cultripennis was described! by Boheman from specimens (or a specimen) sent to 
him by Chevrolat, and I think his description on the whole applies better to the 
species we figure than to any other; and a small series of examples in my own 
collection were so named by the late M. Jekel. The examples of EL. cultripennis in
