 Arthrolips similaris. 

 Oberthuri.

Sericoderus pallidus. 

 I have not seen a type of A. similnrLs, but tbe immense series of A. {Suciwn) Oberthuri 

 taken by Mr. Champion in Central America proves beyond a doubt that that species is 

 liable to vary niiicb both in size and in tbe markings of tbe elytra, and for this rea.son I am 

 inclined to tbiiik that .1. similaris is a variety of .^. Oberthuri. The former of these is thus 

 described by Ilcrr Keitter : — 



" Arthrolips similaris, n. sp. — Oblougo-ovalis, breviter pubescens, fuscus, protborace 

 (macula oblonga in medio .sita excepta) fascia elytrorum transversa communi, extus abbre- 

 viata, paulo pone medium, et margine apicali, pygidio, anteunis pedibusque, plus minusve 

 rufo-testaceis. Long, plus 1 mm." 



To this description he adds that it is "quite like tbe following {A. oherthmi] in form 

 and colour, but smaller, more closely and more finely punctured, and chiefly distinguished 

 by tbe shorter and more silky pubescence ; the spots on the base of the elytra appear to be 

 wanting in this species." 



In Deutsche Eut. Zeitschr. 1884, p. 58, be describes : — 



Sacium Damryi. 

 In Deutsche Ent. Zeitscbr. 1884, p. 117 : — 



Moronillus pumilus. 

 And in Wiener Ent. Zeit. iv. p. 273 (iHHoi:— 



Arthrolips Simoni. 

 Peltinus Matthewsii. 

 ,, alutaceus. 

 It would be useless in this place to truu.scnbe verbatim tbe accurate and satisfactory 

 descriptions of Herr Eeitter, especially since all the species except two will be fully de- 

 scribed in the subsequent pages from authentic types kindly transmitted to me by himself. 



Among tbe foregoing notices of Herr Reitter's publications, I find that I have omitted 

 to mention the following in their proper places : — 



In Deutsche Ent. Zeitschr. 1878, p. 12G : — 



Sericoderus Revelierei. 

 In Deutsclie Eut. Zeitschr. 1H7(;, p. 312; 1H78, p. 199 :—

These arc well described, and tliu distinctive characters of A. humilis clearly defined in
