The sexual characters are the same as ia morio. 



This species is rufo-piceous or rufo-testaceous ia color, somewhat 

 paler beneath than above, often with the margin of the elytra darker, 

 than the disc forming the synonym limhatus, others have the elytra 

 piceous with an oblique paler spot on each and form ohliquus. I can- 

 not find that these differ specifically from iruncatus. It is worthy of 

 mention that in this species the intercoxal process of the prosternum 

 is very narrow even at its tip. 



Very widely distributed, Canada to Florida and Texas, also in 

 California. 



A careful examination based on dissection shows that the males 

 really do have an additional segment beyond the pygidium, which is 

 deflexed so strongly as to become apparently a member of the ventral 

 series. By softening a specimen and gently withdrawing this seg- 

 ment it is found to have a thorough membranous connection with the 

 last dorsal, while the anus is very plainly visible between this small 

 segment and the fifth ventral. From the depression of the body of 

 most of our species, the deception concerning the relationship of this 

 segment is even greater than in Carpophilus^ but in Brachijpeplus the 

 same is again repeated. 



BRACHYPEPL,US Erichs. 



Labrum short, transverse, very feebly emarginate. Antennae with 

 suddenly formed three-jointed club, antennal grooves shallow, con- 

 vergent beneath. Abdomen with three segments exposed beyond the 

 elytra, beneath first two segments short, equal, third and fourth equal, 

 each as long as the first two united, fifth equal to the third and fourth. 

 Tarsi feebly dilated. Body much depressed. 



The males have an additional segment beyond the pygidium 

 which appears equally dorsal and ventral at the same time, but 

 its true nature is that of an ultra-pygidial segment strongly de- 

 flexed as in Carpopliilus, but even more so, with the anal opening 

 between the posterior edge of the fifth ventral and the appendicular 

 segment. 



The affinities of this genus seem to me well marked. It and 

 Conotelus are .slight modifications of one type, and the differences are 

 even feeble and may be narrowed down to an alteration in attenuation 

 and depression and a slight variation in the form of the antennal 

 grooves. Mr. Murray places the present genus in the Late-Jimhriata 

 and Conotelus in Anguste-fimhriata, yet an examination fails to show* 

 any reason for this, for we find that Conotelus steuoides is certainly as
