﻿284 LE CONTE.— SYNOPSIS OF THE 



spurs. Tarsi slender, longer than the tibiae, with verticellate hairs ; ungues diverging, 

 armed with a tooth so long that they appear cleft; onychium short bisetose.

Found at Vallecitas, San Diego Co., California in April, on flowers of a composite 

 plant. I can find no sexual characters in the specimens collected. By examination 

 I find the abdominal stigmata situated in the dorsal inflexed portion of the ventral 

 segments ; the last pair I cannot detect, since the margins of the ventral segments are 

 thin and reflexed above the dorsal surface, so as to produce a concave surface, in which 

 the posterior pairs are concealed. 



9. HOPLI.E. 



This division is known among those having prominent conical anterior coxae by 

 the ventral segments being connate, the sixth indistinct or even invisible ; by the 

 large parapleurse ; the tibiae without terminal spurs or at most with a single very small 

 one, and by the ungues being chelate (*'. e. capable of being folded against the last 

 joint of the tarsi,) not divergent, unequal and without any onychium. 



In this division, though not in any American form, is found a modification of ligula 

 not seen or only exceptionally in any of the preceding tribes : the ligula is membra- 

 nous, and not connate with the mentum : by this character, found in Pachycnemis 

 and allied genera, the passage to the following group is most naturally made. 



The only genus found in our country, and in fact the only one found outside of 

 Southern Africa, is 



Hoplia Illiger.

New Mexico and Kansas ; the anterior tibiae, as in the others of this group, have 

 two large teeth and a small one above, which is sometimes indistinct. The antennae 

 as in the other species are 9-jointed. The scales of the elytra are narrower than 

 those of the under surface. 



2. H. Oregona, oblonga, latiuscula, nigra, breviter pubescens, subtus et pygidio argenteo-squamosa,
