Only one subtropical species represents this large cosmo- 

 politan tribe in the United States and but two genera are known 

 in the western hemisphere. The remainder are Asiatic and 

 African. The comparatively long third rostral segment and 

 the unusually small size of the head for Alydinae are the diag- 

 nostic characters of the group.

Leptocorisa, as indicated by the many references* and 

 synonyms, is a widespread genus with species in all parts of the 

 world. Three of them belong to the western hemisphere, 

 and one has been collected in the United States. The long 

 juga, which exceed the tylus separate it from the neotropical 

 Lyrnessiis.

Leptocorisa crudelis Westwood (1842) 18. 



Description. — Color pale flavescent, marked with olivaceous and 

 rufescent. Head much shorter than pronotum, juga united to tip 

 above tylus, which they slightly surpass. Antennas nearly as long as 

 body, reddish except dark apices of second and third segments. Rostrum 

 with second segment sul:)cqual to two apical segments together: third 

 about as long as fottrth, which is black at tip. 



*A much longer list of references is given by Van Duzee (1917); the ones 

 omitted above are European papers in which American species are not especially 

 considered and in which the terms Leptocorisa and Myodocha are used. The 

 history of the genus name is given by Van Duzee in Can. Ent. 46:378, 379. 1914.
