CHRYSOMELID/E: EUMOLPINI 



head is visible from above although the pronotum comes 

 about to the eyes; the outline of the eyes is more or less 

 indented; the antennas are usually thread-like and widely 

 separated at their bases; the front coxae are globose and 

 separated by the prosternum; the third tarsal joint is 

 deeply bilobed ; the claws, toothed or cleft. The following 

 key will help to identify eight of the genera. For the 

 most part our species are not over .25 in. long. 



1. Front ventral margin of thorax curved, forming 

 lobes behind or below the eyes. (Only those beetles, 

 belonging here, whose elytra are not pubescent or scaly 

 are considered further) 2. 



Front ventral margin of thorax straight 3. 



2. Elytral punctures in distinct, regular rows; middle 

 and hind tibiae indented on outer edge near apex. Typo- 

 plwrus. T. canellus is quite common on a variety of plants 

 and sometimes injurious to strawberries, raspberries, etc. 

 It is exceedingly variable in color and markings, reddish- 

 yellow and black being the usual elements. About all 

 that can be said here is that it is not .2 in. long and bright 

 blue (T. viridicyaneus] , nor has it a saddle-shaped, black 

 space on the elytra (T. sellatus). 



Elytral punctures irregular; tibiae not indented. See 



Plate LXXXI. Usually common on dog-bane 



Chrysochus auratus. 



3. Side-margins of pronotum not distinctly flattened 4. 



Side-margins of pronotum distinctly flattened 6. 



4. Not metallic above; head without a groove above 

 the eyes 5. 



Metallic green or bronzed above; head with a groove 

 above the eyes. Graplwps. The larvae of G. nebulosus 

 live in the roots of strawberries. 



5. Front femora with a small tooth; third joint of 

 antennae not longer than the second. On oak and other 

 trees Xanthonia. 



Femora not toothed; third joint of antennae longer 

 than the second. On grape and Virginia creeper .... Fidia. 



6. Head with distinct grooves above the eyes; middle 

 and hind tibiae indented near apex. On oak and other 

 trees Metachroma. 



Head without grooves above the eyes 7.
