rounded ; median lines and granules very feeble. Elytra 

 conjointly arcuate at base ; with series of large round punc- 

 tures, about the width of interstices, but appearing much 

 smaller through clothing; interstices regular. Abdotne^i with 

 basal segment gently concave. Legs stout, especially front 

 femora ; front coxae moderately separated ; front tibiae mode- 

 rately bisinuat^e beneath. Length, 4J-4J mm. 



Female. Differs in being more robust, abdomen convex 

 throughout, tibiae straighter, etc.

The derm of the elytra, the throat, and other parts of 

 the under surface are sometimes quite black ; but as a rule 

 these parts are of a dark-brown, although usually darker 

 than elsewhere ; the prothorax is very rarely black. The scales 

 are often rather strongly variegated, and there is usually a 

 distinct white spot on the third interstice at base, and also at 

 the side of each eye, somewhat as in alhonotatus. On some 

 sjoecimens the scales are almost entirely dark, with more or 

 less conspicuous whitish spots. The clothing of the abdomen 

 consists of rather dense setae, but with scales at the sides of 

 the two basal segments. The front coxae are very distinctly 

 separated, but the distance between them is less than in most 

 species, and is less in the male than in the female. It is, 

 however, slightly more than in jmllidvs and SKturalis, which 

 species have been referred to another section in the table. 



The prothoracic granules, although individually rather 

 large, are quite invisible before abrasion, and are even more 

 feeble than in alhonotatus; in fact, from some directions the 

 prothorax, even after abrasion, appears to be without them, 

 but in certain lights very fine lines can be seen marking their 

 edges ; alhonotatus, which it strongly resembles, has the pro- 

 thorax larger, with a more distinct median line, the front 

 coxae more, and the middle coxae m.uch more, widely separ- 

 ated, the abdominal clothing sparser ; and is altogether more 

 robust. The mandibular appendages are present on one 

 female before me. and are lone, thin, and curved, much as in 

 many species of Leptopa. 



SUB-FAMILY EURHYNCHIDES. 



Ctenaphides gymnostictus, n. sp. 

 Female. Dark reddish-brown. Densely covered with 

 whitish setae-like scales, almost uniform in distribution, except 

 that the apical half of the rostrum is nude, and that there are 

 nude spots forming rows on the alternate interstices of the 

 elytra, the spots being more numerous on the sutiiral inter- 

 stice than on the others.
