Tlii.s insect lias been very rare in collections, only two or three 

 specimens nntil recently beiiiii- known. I owe mine to the kindness 

 of Mr. Blanchard, who foinid several si)ecimens near Iliiihlands, 

 N. C, rnnning on the branches of oaks. It is black, the head and 

 prolhorax densely coar.><ely i)unctiired, the elytra less densely punc- 

 tured, shinino;, with short liairs proceedino; from the punctures. The 

 prothorax is as wide as the head, with an acute lateral spine rather 

 in front of the middle. The resemblance to Moiiilema and Cyrtlnii^ 

 is very nnirked, and it shares the ant-like habit of the latter when 

 seen runniiiii' in lite. It lacks, however, the essential characters of 

 the subfan)ily Lamiinie, viz. : the sulcate tibiae and the slender palpi.

 thiini ; but Michthysoina does not present an assemblage of feeble
