Elytra 



Except for color patterns mentioned above, the elytra 

 have few useful characters. One is the number of elytral 

 striae and the strength of the strial punctures. Most 

 species have seven complete striae; stria I next to the 

 elytral suture, striae V and VI originating at the humerus. 

 Stria VIII on most species is reduced to a short row of 

 punctures visible at the basal quarter under the humerus 

 and/or the apical quarter near the lateral edge of each 

 elytron. Two species (I. n. sp . 6 & I. n. sp . 7) have 

 stria VIII complete, one species (I. n. sp. 1) has parts of 

 stria IX visible. 



The size of the strial interval punctures is variable 

 from species to species. In the majority of species the 

 punctures are small and obscured in the microsculpturing. 

 In a few other species they are large and distinct, 

 occasionally obscuring the strial punctures. 

 Ventral Lines 



A "line" refers to a ridge or fine groove on a 

 sclerite that is not a suture, but probably has some 

 supportive function. These lines surround the coxae and 

 often extend onto the sclerite (Fig. 9) . The term "coxal 

 line" is used in reference to the line on the median side 

 of the coxa. The lines anterior or posterior to the coxae 

 are referred to by the structure they are on or near; e.g.,
