BALANINl\s (icniKu. 



The genus Halanimis coinpinses nearly fift}' species, most of which 

 Ix'loni;- to the iiortlii-rn hcinisphere; in America, where eight s])ecies occur, 

 none are toiiiid soutii ot tiic Tiiited States. A couple ot' species have been 

 found fossil in Pjurope, one at Aix and one at Kutschlin. while in Aniencji 

 no less than six species occur and are t'oiiiid excliisiAci\- at Florissant, so 

 that the srenus mav be regarded as ver>' characteristic of the Lacustrine 

 fauna. The Kutschlin species, I>. f/e'mitzi Deichmiiller, seems to be not far 

 removed from our />'. miiiusciilus. 



The species here referred to Balaniniis diffiT from modern t\ pes in 

 the brevity of the rostrum, which nevertheless is longer than in n(*arly all 

 other fossil Rhvnchophora. Whether or not males onlv have been found 

 can hanllv Ix; told, V)Ut in no case does the rostrum nearly e(j|Ual the body 

 in length, and iu some it is onl)- half as long. 



Tahh of the species of Balnnhuis. 



Hostnim only alxitit half as Vma as the body, or less. 



Kostruin much louger tlian head and prothorax together. 



Basal half of rostrum considerably arcuate aniviiltiiis. 



Basal half of rostrum nearly straight. 



Lartrer species with coarse markings; rostrum gently arcuate, .nxlrictitx. 

 Smaller species with tine markings; rostrum strongly arcuate, wi/hiwch/k.s-. 



Rostrum no longer than head and prothorax together .J'emoratus. 



Rostrum about two-thirds as long as the body. 



T^arger spe(;ics, with rcgnlaily and moderately ai-cuate rostrum ihiffoiii. 



Smaller species, with strongly arciuite rostrum, bent in the middle so that the two 

 ends are nearly at right angles Jledirostriv.
