tennal joint, complete absence of scutellum and absence of all trace 

 of a dilated post-coxal plate on the first ventral segment, and sug- 

 gests certain types of the latter by the excessively small or obsolete 

 mes-epimera. It however differs from both in the compressed body, 

 more transversely elongate and more narrowly separated hind cox«, 

 narrow^er met-episterna, narrowed posteriorly and not anteriorly, in 

 the still longer tarsi and longer tibial spurs, in having the large 

 side-piece of the mesosternum clearly separated by a longitudinal 

 suture near the coxae, and in the fact that the sutural stria of the 

 elytra does not attain the base. 



Our two species are very strongly differentiated but cannot be 

 separated generically ; they may be defined as follows: — 



Basal angles of the prothorax only very feebly produced, obtusely angulate, 

 the side-margin of the prothorax attaining their apices ; metasternum gen- 

 erally with a cluster of four or five coarse punctures near the middle coxae. 



gaiumaroides 



Basal angles not at all produced, obtuse and somewhat blunt; side-margin of 

 the prothorax rapidly deflexed, meeting the sides of the pronotum far in 

 front of the basal angles, the intervening edge upwardly oblique ; meta- 

 sternum coarsely, deeply punctured throughout COmpressuiU 



In gamwaroides there is a slight downward flexure in the acute 

 lateral margins of the prothorax opposite the point where these 

 margins terminate in compi-essum, suggesting a merely less de- 

 veloped form of the same structure.

Narrow, polished, scarcely punctate, black; tip of abdomen, legs 

 and antennee rufous. Antennae slender, nearly as long as the head 

 and prothorax, the third joint slender, almost four times as long as 

 ■wide, shorter than the fourth, the latter not as long as the fifth but 

 equal to the sixth; seventh slightly stout; eighth more slender; 

 club moderate in length. Met-episterna posteriorly only one-half 

 as wide as near the base; suture coarse and deep; epimera small, 

 extending inward far within the episterna, meeting the tips of the 

 hind coxae. Length 1.6-1.8 mm.; width 0.7-0.^5 mm. 



Rhode Island and New York; LeConte indicates ''Southern 

 and Western States," but may have confounded the next species.

Greatly resembles the preceding but rather shorter, broader and 

 dark red-brown in color. Besides the characters already noted
