The head is evenly ami rather strongly punctured, witii 

 much less distinct j»unctuation on the clypeus ; the clypeus 

 has the angles ot" the eniargination distinctly but slightly 

 dentiform ; hallway between this angle and the posterior 

 angle there is a very slight sinuosity. The thorax is evenly 

 convex, without any swelling in front, a little constricted at 

 the base, areuately narrowed at the anterior angles, evenly 

 and strongly punctured; at halt'way towards tlie side about 

 seventeen jmnctures may be counted in a line from the front 

 to the posterior margin ; the ])unctures are deep, separated 

 from each other by about one half the diameter of a puncture. 

 The elytra have the strife rather fine, with the punctures in 

 them not very close together ; the first interstice is rather 

 closely punctured, the second is irregidarly punctured for the 

 basal half and then (like the other interstices) has two lines ; 

 these punctures are rather small, and leave a rather wide 

 smooth space in the middle of the interstice ; below the 

 shoulder there is a line of about five small shining tubercles, 

 and on the ninth interstice a longer line of more distant 

 tubercles ; these tubercles are visible when viewing the insect 

 from above. 



Aphengium. 



I have just had an opportunity of examining the type of 

 Aphengium seminudum , Bates (Biol. Centr.-Amer., Coleopt. 

 ii. 2, p. 42), and it appears to have been placed in this genus 

 by an oversight. In characterizing the genus Harold says, 

 *' Tarsorum posticorum articulus primus sequenti longitudinc 

 multo longior ; pygidium rectum. Segmenta abdominaiia 

 connexa" (Col. Hette, iii. p. 54). A. seminudum has the 

 abdominal segments free ; the pygidium is completely turned 

 under, so that its apex is directed forwards, and Mr. Bates 

 observes, " The short and broad, compressed and subtrian- 

 gular tarsal joints are a remarkable distinguishing feature. 

 The anterior cavity of the j)rosternum is exceedingly deep." 

 These characters appear to me to conform more with Bdelyrus, 

 Harold (Col. Hefte, v. p. 97), of which Harold says : " Clypeo 

 antice angustato et breviter bidentato. Prosternuni antice 

 profundissirae foveolatum. Segmenta abdominaiia suturis 

 distinctis. Pygidium contractum et abdoniini appositum. 

 Tarsi postici dilatati, compressi, articulis latitudine sensini 

 decrescentibus." The clypeus has a projection in the 

 middle, and in fresh s])ecimens this is slightly bidentate ; 

 this seems to agree with Harold's character.
