As in the last paper published in February, I again give a 

 I'late to facilitate the identification and call attention to 

 a few peculiar forms. I have also introduced three more 

 descriptions by other authors for aiding references. Tliis 

 paper is the forty-second of the series, which must necessarily

 1 do not propose to include any of these species in Graynmo- 

 stetkus, as the species of the latter genus are Oriental, and 

 have, in addition to the prosternal stri«, several other notable 

 characters, such as the rudimentary stria at the base of the 

 fourth dorsal stria (Ann. Mus. ('iv. di Geneva, xxxii. p. 28, 

 1891). Dr. G. H. Horn has a note on the striation of the 

 prosteruuni in the genus Ilister (Trans. Amer. Soc. vii. p. 1,
