tibiis extus spinulosis, tarsis anterioribus similibus sed art. 1-3 minus 

 dilatatis, cordiformibus. Prosternum marginatum, punctatum, obtuse, 

 acuminatum. Mesosternum antice carinatum.

Of the usual shape and color, but larger than usual, vary- 

 ing, however, in this respect, some individuals being fully one 

 third smaller than others. These small individuals, which 

 occur in the proportion of about 2 to 20, are moreover nearly 

 always of a brownish metal color instead of a blackish green. 

 I have been unable to discover any other distinctions. This 

 difference in size is no criterion as to the sex. The insect 

 appears of local occurrence or attached to certain plants, 

 which is nearly the same. I find them in abundance in 

 the blossoms of Convolvulaceous and Apocynaceous plants 

 in my garden, which is situated in the west bank of the 

 lake. The species appears to differ from the typical 

 Meligethes in the following points: the structure of the 

 mcntum, which 1 have sufficiently described above, the last 

 joint of the lab. palpi, which in this case is not truncated, and 

 the first of the antenna? which is externally incrassated as in 

 Epuroaa. The antennas are otherwise robust, the club is 

 firm and hairy. The thorax is very ample, thinly ciliated 

 along the upper part of the anterior margin, rather strongly 

 below. The prosternum is largely developed, marginatcd, 

 punctured and obtusely acuminated, overlapping the anterior 

 part of the mesosternum which (the anterior part) is cylin- 

 dric and carinated. Joints 1-3 of the tarsi are strongly 

 penicillated below, the penicilla being composed of glanduli- 

 ferous hairs of a fine golden color.
