has four diverging minor ridges radia- 
ting from the middle ridge (fig. 1); and 
the reticulations of the elytra between 4 
each ridge are singly scalariform, as shown Bi 
in fig. 2, and not doubly scalariform as ~ 
in the next species.

Mr. Thomson’s description of what Fig. 3. 
I suppose to be this is as follows :— 
‘“‘ Above yellow, with the middle of 
the prothorax, the scutellum, and a little 
more than the posterior third of the 
elytra black; below, legs and antennz 
black, as well as the base of the thighs, 
the middle of the metasternum and the 
last article of the antenne yellow. 
“Very elongated, slender, parallel. Antenne very broad, 
with prolonged articles diminishing towards the extremity ; 
prothorax angularly rounded in front, in the middle a ridge 
changing behind into-a broad groove. LElytra straight on the 
sides, having each three strong ridges; intervals reticulated. 
“ Length 74 mill., breadth 2 mill.” 
The only difference between this and the description of the 
preceding species is that, while the elytra of LZ. sulczcolls have 
four strong ridges with the intervals “regularly reticulated,” 
this has only three strong ridges with the inter- 
vals “reticulated,” and that the scutellum of this 
species is black, while that of the other is not. 
The difference in reticulation is not alluded to; 
but the reader will see, on comparing fig. 4, which 
shows it in this species, with fig. 2 in the last, 
that it is an excellent distinction. 
Iam in doubt whether any difference is meant to be implied 
by the use of the different expressions “reticulated” and 
“yegularly reticulated; but the single scalariform interval 
appears more suggestive of regularity than the smaller and 
closer double scalariform interval, which is necessarily more 
crowded ; and on that ground I have referred the “ regularly 
reticulated” to LZ. sulcicollis ; and I am the more supported in 
doing so by the scutellum (or, rather, the scutellar region) 
being black in it. The numerical difference of three strong 
ridges instead of four I cannot find: they all have four; and
