costatus Barbaria." I have seen no specimens from anywhere but 

 North Africa, generally merely labelled "Algeria" ; it has been found by 

 M. Thery at St. Antoine and St. Charles. "It varies a good deal in size. 

 The aedeagus shows very little distinction from that of T. alfernans, 

 the lateral lobes are perhaps a little longer and more slender.

Eather larger and darker in colour than T. alternans, and with the 

 epipleura differently formed, and making an approximation to Meghelo- 

 pJiorns thereby. The palpi are normal for Trichelophorus. Thorax 

 shaped as in T. alternans, but with the front angles more produced ; 

 the grooves as in alternans, but the setosity reduced. Elytra with the 

 intra-humeral callus not very prominent, the alternate interstices 

 elevated more distinctly behind than in front, setosity much as in 

 alternans but shorter, accessory punctures three or four on each side. 

 Under-surface black. I have seen only one example. In this interest- 

 ing form the pubescent epipleura are long and intermediate between 

 those of Trichelophorus and MeghelojyJtorus, and the pseudepipleura 

 are likewise intermediate. 



The locality is a little doubtful. I received the specimen about 

 forty years ago from Dr. Millingen in a box of pinned and mounted 

 insects collected by him in Egypt, Mesopotamia and Arabia. A few 

 of the specimens had come loose in the box, and I replaced them as 

 best I could, labelling this one " Egypt ? " If not from Egypt, it is 

 from Mesopotamia or the Hedjaz. It is so very like the Hedjaz 

 exponent of Eutrirhelophorus micans that accompanied it as to suggest 

 that it may have come from the same locality.
