Many of the species of this genus are so much alike 

 that it is difficult to distinguish them by the most minute 

 description ; and I confess that, although I have described 

 the insect under the above name, I am in doubt, because 

 Dr. Snellen van Vollenhoven, in his Faun. Ind. Neerl., 

 iii., p. 17, 2 (1868), described a species under the name 

 of .E. jxdlidicornis, which in many points agrees with the 

 above. I wrote to him for the loan of an example, for 

 comparison, but unfortunalely he died, and so I never 

 received it. I have only a single example, but without 

 note of locality. 



Family Pentatomid^. 



Genus Alcimus, Dall. 



A Icini us japoncnsis. 



Flavous, thickly black-punctured, the punctures run- 

 ning in short, irregular, confused, frequently- curved 

 strise. Head almost perpendicular; base of the central 

 lobe, with a round unpunctured space, and a narrow, 

 longitudinal stripe on either side, also unpunctured ; next 

 the inner margin of each eye a somewhat reniform flavous 

 2)atch. Antennce pitchy-brown. Pronotum, jDosterior 

 angles reflexed and produced into a spine having an 

 acute tooth a little way before the apex of the anterior 

 margin, SetiteUum with a flavous spot within each 

 basal angle. Corium, nerves pale flavous. Membrane 

 brown. Legs flavous. Thighs with pitchy-brown punc- 

 tures, except the base and apex. Tibioi brownish yellow. 

 Tarsi piceous, 1st joint underneath thickly clothed with 

 short pale yellowish hairs. Abdomen underneath flavous, 

 sides faintly punctured, the punctures fading before 

 reaching the middle, down which is a broadish pitchy- 

 black streak ; genital segment pitchy-black. Head 

 flavous, almost perpendicular, thickly black-punctured.
