Castanea pumila. This species seems to be similar to A. museorum ; but I 

 cannot discover any sexual differences in a large number of specimens examined. 

 The antennae are sometimes dark-colored towards the extremity; the feet also 

 vary in color, the thighs being usually darker than the tibiae and tarsi : the elytra 

 are generally uniform testaceous brown, sometimes the margin and suture are 

 dark fuscous. 



Apsectus Lee. 



Caput prosterno receptum ; oculi magni, ocellus frontalis ; mesosternum trans- 

 versum hand emarginatum ; antennae tenues, clava 3-articulata, scrobiculis male 

 definitis receptae ; pedes tenues, tibiis linearibus, antici modice distantes. 



A curious little insect, covered with long erect hair, and presenting the ap- 

 pearance of the European Trinodes ; the antennae are precisely as in that genus ; 

 the prosternum, however, is truncate behind, and the anterior coxae are moderately 

 separated; the mesosternum is short, transverse and rounded anteriorly, while 

 in Trinodes it is cleft as in Anthrenus, Trogoderma, &c. The legs are slender, 

 the tibiae not dilated; the joints of the tarsi diminish in length from the first to 

 the fourth, the fifth is about equal to the first. In all other characters it agree 

 with Trinodes. 



1. A. h i s p i d u s, ovalis, modice convexus, niger nitidus pilis longis erectis 

 nigro-cinereis vestitus, thoracis lateribus rectis submarginatis, elytris parce 

 punctatis, antennis piceis basi pedibusque fiavis. Long. -05 8. 



Syncalypta hispida Melsheimer, Proc. Acad. Nat. Sc 2, 117. 



Middle and Southern States, on leaves, not abundant. A specimen kindly 

 given me by Prof. Haldeman was hatched from a protuberance on the stem of 

 Rhus radicans, but as some small Hymenoptera emerged from other similar ex- 

 crescences, I think that the relation of the present genus to them is very doubtful. 



The last joint of the antennae of the male is elongated, so as to be nearly 

 equal to the others united. 



Varies in color, having the head, thorax and margin of the elytra occasionally 

 yellowish brown.

Erichson, Ins. Deutschl. 463. 



Middle and Southern States, on flowers. In comparison with the European 

 0. glabratus, Erichson observes, that this one is one half smaller, less shining, 

 with the thorax more convex and more finely punctured, and with the elytra 

 more thickly punctured, and somewhat rugous.
