outermost costae uniting posteriorly and forming a slightly projecting 

 angle at the apex ; antennae and legs dark ferruginous, shining ; body 

 beneath shining, dark reddish-brown, with small oblong impressed spots. 

 Length 4 lines. 



Anarmostes [Colydiidae]. 



Head subquadrate. Antennae short, eleven-] ointed, the two basal incras- 

 sated, the third longest, the rest gradually decreasing in length to the 

 eighth, the last three forming an ovate, compressed, perfoliate club. 

 Eyes large, round, slightly divided in front. Maxillary palpi sub- 

 cylindric, the last joint obliquely truncate, the labial smaller, subacurni- 

 nate. Prothorax elongate, narrower posteriorly, deeply sulcate, not con- 

 tiguous to the elytra. Scutellum punctiform. Elytra elongate, nearly 

 parallel, ribbed, wider than the prothorax. Legs short ; coxae not con- 

 tiguous ; tibiae spurred, somewhat dilated and more or less toothed 

 externally near the apex ; tarsi slender, hairy beneath, the basal joint 

 subelongate. Prostemuin prominent, keeled in the middle. Abdominal 

 segments gradually diminishing in size. 



Allied to Sosylus, with which it also agrees in habit, but at once 

 distinguished by its triarticulate club and sulcate prothorax. I have 

 not dissected the mouth of my specimen (which I owe to the kindness 

 of Mr. Fry, by whom alone, I believe, it has been taken) ; but the 

 mentum seems to be very small, and attached internally to the large 

 subquadrate jugular plate, which M. Lacordaire has, apparently, 

 denominated the "sous-menton" ; the point of insertion of the palpi 

 is, however, not covered by it, but is more than usually obvious. 



Anarmostes sculptilis. (PI. VIII. fig. 8.) 



A. elongatus, piceo-fuscus ; pedibus rufo-piceis. 



Hah. Brazil (Rio). 



Elongate, dark pitchy-brown ; head and prothorax covered with 

 numerous impressed punctures, with a very short hair-like point in the 

 centre of each, the latter with five deep longitudinal grooves ; scutel- 

 lum hollowed out in the middle ; elytra about three times the length 

 of the prothorax, each with five strongly marked costae, the intervals 

 with a double row of elongated punctures, giving the spaces between 

 them a granulated appearance ; antennae much shorter than the pro- 

 thorax, yellowish-red ; legs dark pitchy-red ; tibiae finely ciliated and 

 armed externally at the base with three or four teeth ; body beneath 

 coarsely punctured, the abdominal segments with numerous fine, longi- 

 tudinal, but more or less interrupted lines. Length 4± lines. 



Asprotera [Colydiidae]. 

 Head rather narrow, depressed, slightly expanded at the sides over the 

 antennae. Eyes large, round, with a deep antennary groove beneath. 

 Antennae short, ten -jointed, the first two incrassated, the remainder
