Genus Liburniella Crawford. 
This is a good genus sufficiently distinct from Liburnia Stal. 
L. ornata Stal. is the only species known to me. 
Genus Stenocranus Fieber. 
S. saccharivorus Westw. is a light green insect, not “yellowish- 
orange” as described by Crawford. His specimens may have 
been in spirits. It was common about sugar cane in Jamaica and 
I took it at Tampa, Florida. 
Stenocranus croceus Van Duzee. This species is here wrongly 
credited to Osborn and Ball, who merely listed the species but did 
not describe it. Their paper was published in 1897, not 1896. 
This is a true Kelisia as described by me, and has the front dis- 
tinctly wider than in Stenocranus with the sides arcuated. 
Stenocranus vittatus Stal is undoubtedly the same as my lautus 
and both are probably mere color varieties of dorsalis Fitch. 
Genus Dicranotropis Fieber. 
The genera Peregrinus and Pissonotus are entirely distinct from 
Dicranotropis and may at once be distinguished by the characters 
of the pronotal carine: In Perigrinus they run straight to the 
hind margin, while in Pissonotus they are more divergent and 
rarely attain the hind margin. In Dicranotropis these carinz 
follow the contour of the eye. The general aspect of Pissonotus 
is very distinct, approaching only Megamelus. Mr. Crawford 
sinks my basalis as a synonym of delicatus but it is absolutely dis- 
tinct. The Columbus, Texas, specimen which he examined was 
not typical of the species as I stated in my description. I do not 
think I labeled that specimen as a “‘type.”” If I did it was done 
inadvertently. 
Genus Megamelus Crawford 
This genus as outlined in the work before us contains at least 
six undoubtedly valid genera: Megamelus, Kelisia and Prokelisia 
with the lateral pronotal keels running straight to the hind margin, 
and Euidella, Chloriona and Liburnia in which they curve outward 
behind the eyes. In his key the author divides his unwieldy genus 
into these two sections and under each uses color characters first 
and ultimately structural features for locating the species. I have 
not tried to run down any of the species by his key but it would,
