LOBIOPA.—SORONIA. 323 
Under this name I separate some examples that, besides being smaller than the 
smallest individuals of Z. decumana, differ in the sides of the elytra being less 
explanate, the epipleure narrower, and the eyes beneath shorter in the longitudinal 
direction, and therefore approaching a semicircular form. These examples more 
nearly resemble Z. cassidoides, but they have the disc of the thorax more coarsely and 
not quite so closely punctured, and the erect pubescence on the mentum and gula is 
not present, and the lobe behind the eye is small. ZL. precox, Er. (Germ. Zeitschr. iv. 
p. 297), from Brazil, may possibly be a variety of either LZ. simulatrix or L. cassi- 
doides, but I think from the description it is more probably a distinct species. In 
L. simulatrix and LZ. cassidoides the lobes over the insertion of the antenne are much 
less prominent than they are in L. decumana. 
6. Lobiopa discedens, sp. n. (Tab. X. fig. 18, ¢.) 
Suboblonga, parallela, parum convexa, picescens, antennis pedibusque piceo-rufis, elytris ferrugineo-variegatis ; 
prothorace dense sequaliter punctato; elytris subrugulose punctatis; corpore limbo minus late explanato 
sed intra marginem magis depresso. 
Long. 54 millim. 
Hab. Guatemata, Capetillo (Champion). 
Basal appendage of antenne large; eyes large and conspicuous. Thorax rather 
deeply and abruptly emarginate in front; sides a little narrowed towards the front, 
but, except for this, nearly straight, rather deeply and definitely depressed within the 
lateral margin; the surface closely and evenly punctured, very finely pubescent, with 
two or three vague depressions near each side. Elytra rather closely and finely but 
subrugosely punctate, the serial sete fine and curvate; variegated with some red marks 
near the base and beyond the middle; and, like the thorax, deeply depressed within 
the lateral margin. Prosternum not at all impressed between the coxe. Legs rather 
widely separated. Male with the inner margin of the hind tibize excised at the base. 
This species was procured in considerable numbers. It is perhaps entitled to generic 
distinction owing to the abdominal lobe between the hind coxe being broad and 
truncate, and the inner epipleural margin continued to the suture, the epipleura being 
in this part, however, so narrow that there is only just space on it for a series of fine 
punctures, 
SORONITA. 
Soronia, Erichson, in Germar’s Zeitschr. iv. p. 277 (1843). 
This genus, after subtraction of Phenolia, Lobiopa, and Amphotis, which have been 
included in it, will comprise eight or nine species distributed in the Palearctic and 
Nearctic Regions, and with species in New Zealand and New Caledonia, which latter, 
however, will have to be removed. It is doubtful whether Soronia really occurs within 
our limits.
