1. Soronia rectangula. 
Seronia rectangula (sic), Reitter, Verh. Ver. Briinn, xiii. Abhandl. p. 102°. 
Hab. Mexico, Teapa?. 
Reitter, who united Lodiopa with Soronia, states! that S. rectangula is a true 
Soronia, but I greatly doubt whether he was correct in so doing. If the insect is 
really a Soronia I am certainly unacquainted with it; if not, it may be L. discedens. 
CACCONTA, gen. nov. 
Sulci antennarii parum convergentes. Palpi labiales dilatati. Prosternum inter coxas rotundatum, haud 
prolongatum. Tarsi elongati, lineares. 
I establish this genus for a species of which we have received but a single exponent. 
The parts of the mouth are small, the mentum very small. The eyes as seen beneath 
are small, subhemispheric. The antennary grooves are sharply defined internally by a 
raised line which extends backward along the large submental area; but externally they 
are not definitely limited, though there is a large depressed space behind the eye. 
There are no antennary lobes, so that on the upper surface the base of the antenna is 
quite exposed. The mandibles are concealed by the labrum, which is moderately large, 
feebly emarginate in front. The front coxe are large, transverse, not at all prominent ; 
the prosternum is gently bent upwards in a curve behind the coxe, and its apex is 
concealed, not prominent. The legs are slender, the femora not grooved beneath, the 
tarsi long and slender, the claws large. The hind coxe are not widely separated. 
Cacconia differs from Soronia and Lobiopa by the want of antennary prominences and 
by the prosternum being curved upwards behind the coxe; it agrees with Lobiopa in 
the epipleure being not continued along the apex to the suture. In the structure of 
the head and antenne it comes nearer to Phenolia, but differs from that genus in the 
unmargined femora, the more approximate coxe, and the form of the apical portion 
of the epipleure. 
1. Cacconia obscura, sp. n. (Tab. X. fig. 19.) | 
Breviter ovalis, subconvexa, irregulariter punctata, parce minus subtiliter pubescens, sordide testacea; pro- 
thorace irregulari, lateribus explanatis. 
Long. 4 millim. 
Hab. Mexico, Jalapa (M. Trujillo). 
Antenne with the first joint a little dilated, much longer than broad, the club elon- 
gate, infuscate. Thorax deeply emarginate in front, the anterior angles obtuse, the 
surface irregular, the sides explanate, the punctuation rather coarse, moderately close. 
Scutellum rather large, impunctate. lytra with feeble indications of longitudinal 
coste, coarsely, irregularly punctate, the punctuation obsolete towards the suture ; 
among the scanty hairs there are a few, differing but little from the others, arranged in 
a serial manner.
