:at the basal third ; in the male the swellings there are scarcely 

 traceable. The elytra, in addition to having strongly ronnded 

 sides, slope upwards from the base, so that when viewed from 

 the sides they appear to be conspicuously elevated above the 

 prothorax. In consequence of the median impression the basal 

 segment of the male abdomen appears to be bilobed. 



EURYPOBOPTERUS CRYPTODERMUS, n. Sp. 



S . Black ; antennae and tarsi red. Densely clothed with 

 muddy-brown scales; interspersed with numerous stout, sub- 

 erect ones, in places compacted into fascicles. 



Head with very dense, concealed punctures. Rostrum 

 rather long and thin, sides lightly incurved to middle ; with 

 dense punctures throughout, but more or less concealed behind 

 antennae. Antennae thin ; scape inserted about one-third from 

 apex of rostrum, Prothorax strongly transverse, base strongly 

 bisinuate, sides strongly rounded, surface uneven ; with four 

 feeble fascicles across middle and two at apex ; with rather 

 large, irregular, concealed punctures; and with a thin, con- 

 cealed median carina. ScuteMum not traceable. Elyfra short, 

 base strongly trisinuate, with shoulders strongly produced, 

 sides gently rounded to beyond the middle ; with rows of large, 

 rounded, more or less concealed punctures ; third and fifth 

 interstices each with a distinct fascicle at summit of posterior 

 declivity, some feeble ones elsewhere. Punctures of under- 

 surface concealed. Two basal segments of abdomen large, first 

 as long as three following combined; a deep groove on each 

 side of base, flattened or feebly depressed in middle. Legs 

 rather short; femora feebly grooved, edentate, hind pair 

 scarcely extending to apical segment. Length, 6-7 mm. 



O . Differs in having the rostrum somewhat thinner, 

 shining, with less of the base concealed, antennae inserted not 

 quite as close to apex of rostrum, and basal segment of abdo- 

 men gently convex.

Of the species previously referred to the genus the fascicles 

 would associate it with annulipes and tenuifasciatiis ; from the 

 latter it is readily distinguished by the edentate femora, but 

 the antennae are quite as thin as in that species : from the 

 former it is distinguished by the very different base of elytra. 

 The clothing is so dense that the prothoracic punctures are 

 entirely concealed, and even many of the large elytral ones. 

 On the under-surface the sutures between the metasternum 

 and its episterna are concealed. From some directions the 

 second joint of funicle appears to be distinctly longer than the 

 first, but the two are really of almost exactly the same length.
