Caccothryptus, n. gen. 

 Corpus ovale, compete turn, setosum. Antenna; fragile*, haud clavata, 

 ll-articulata, articulis secundo tertioque elongatis subeequalibus, secundo 



pendulum deplanato, parum discrete curvato. Caput ad retractionem in 

 thoraecm satis adaptation. 



This genus lias an extreme resemblance in appearance and in most of its cha- 

 racters to the Central American Enthryptus, but it differs in the eyes being largely 

 visible from above, in the elongate third joint of the antenna?, and in the greater 

 width of the ligula and maxillary palpi. Although the exposure of the eyes, and 

 the fact that the head is only imperfectly retractile, differentiate the genus from the 

 normal Lhnnichini, yet I think there can be no doubt that it belongs lo that 

 subfamily. The mode of packing the legs and the structure of the hind femora are 

 those characteristic of, if not absolutely peculiar to, the Limnichini. The pro- 

 sternum is large, somewhat pendant in the middle in front, and its broad process 

 fits very accurately into the mesosternal cavity. The middle cox® are widely se- 

 parated. The first ventral segment is rather short, so that the trochanters are but 

 little distant from its hind margin. The hind coxae are flattened and dilated in 

 front, so that the portion received into the coxal groove is very different in plane, 

 in sculpture, as well as in clothing, from the part that remains exposed when the 

 limb is contracted. 



Caccothrtptus compactus, n. sp. 

 Ovalis, sat eonvexus, niger, via- subanescens, pube Jlavo-grisescente macu- 

 latim vestitus ; elylris fortitev irregulariter punctatis ; antennis pedihusque 

 fuscis, sub/la veseentibus, tarsis rufis. Long., 4g mm. 



Antennae slender, rather long, very loosely articulated and fragile, second joint 

 long and slender, slightly longer than the third, terminal joint just perceptibly 

 broader than the preceding one. Head densely and finely punctured, setose. Thorax 

 strongly transverse, continuous in outline with the elytra, closely and finely but 

 somewhat irregularly punctured, pubescent. Elytra with very numerous large and 

 deep punctures, not arranged in regular series, though an imperfect seriation exists ; 

 rather densely pubescent, the pubescence arranged and coloured so as to give rise to 

 a faint spotted appearance.

This is the largest and most remarkable of the Limnichini. 



Ctphonichus orientalis, n. sp. 



Ovalis, eonvexus, nigerrhnus,pube erecta fusco-griseseente vestitus, par ee 

 punctatus, nitidus, pedibus rufis; antennis fusco-rufis . Long., 3 mm. 



Antennae very slender and fragile, each joint longer than broad ; the terminal 

 joint a little longer than the preceding one. Thorax much narrowed in front, bi- 

 sinuate at the base on each side in adaptation to the form of the elytra, finely, 

 rather sparingly punctate, shining, although rather densely pubescent. Elytra 

 shining, sparingly punctate, the punctures very fine, but on the basal part with 

 larger punctures subseriately arranged. The pubescence is rather abundant, sub- 

 erect, dark in colour though not black, and not at all maculate.
