the first week after felling and continued to come for nearly 
a month. It bred abundantly in the Triplaris. The beetles 
are diurnal and may be seen hovering and dipping over the 
dead wood like Vespidse. There is one vespid which they 
very much resemble and which sometimes occurs with them. 
The beetles were caught or bred out in January, March, 
May, June, July and December, so the species is probably 
multiple-brooded. Four specimens were taken in June near 
Santa Marta, on wood which was not Triplaris, but they 
may not have been breeding in it. 
The two following species behave like this undescribed 
Odontocera, to which they are closely related. They were 
so scarce by comparison, however, that they furnished only 
scanty data. 
8. Odontocera fasciata 01. (det. Fisher). Eleven speci- 
mens were taken in January, May and December. Some 
were breeding with No. 7, some flying to dead Triplaris. 
9. Odontocera, sp. nov. (being described by Fisher). 
Five specimens were cut from dead Triplaris with No. 7 
in May. 
10. Amphicerus cornutus Pallas (det. Fisher). This 
large bostrychid beetle appeared on the dead Triplaris Jan- 
uary 15, about a month after felling. The first specimens 
were cut from tunnels which entered the hard wood of the 
trunk at right angles, but curved around parallel to the 
grain at a depth of about half an inch. On February 17, 
two months after the tree was felled, five of these beetles 
were cut from the ramifications of a single tunnel system. 
The tunnels were, of course, made entirely by the adults 
and no sign of eggs or larvae could be found. Two speci- 
mens were taken at Santa Marta in May, probably at light. 
11. Dendrobiella sericans Lee. (det. Fisher). This 
small bostrychid was first noticed during the third week 
after the Triplaris was felled, when adults were boring 
into the dead trunk. The species was common. 
12. Scalidia sp. (det. Fisher). This cucujid appeared 
with the small bostrychid (No. 11), on which it probably
