meeting iu the depression between the antennal tubercles, the latter large, 

 prominent, each crossed by the usual fine groove ; vertex between the foveae 

 somewhat rugose, strongly convex ; antennae stout, not quite as long as the 

 head and prothorax ; under surface with a few erect setae. Prothorax as long 

 as wide, widest at apical fourth where the sides are broadly rounded to the 

 apex, moderately convergent and nearly straight in basal three-fourths ; discal 

 impression elongate ; transverse sulcus and foveae deep and well developed ; 

 surface subimpunctate but sparsely punctato-rugulose between the sulcus 

 and the base. Elytra not quite as long as wide, one-third longer and two- 

 thirds wider than the prothorax, the sides feebly divergent, broadly arcuate, 

 each with two large and very deep basal foveae, the second continued poste- 

 riorly by a broad gradually evanescent groove, vanishing before the middle ; 

 sutural stria entire. Abdomen longer than the elytra and fully as wide, the 

 sides very feebly arcuate ; carinae of the second dorsal very short but distinct. 

 Last three ventrals together about equal in length to the second, two to four 

 uniformly and very slowly decreasing in length. Length 1.25 mm. ; width 

 0.35 mm.

Readily distinguishable from the female of similis (= tibialis 

 Csy.) by its smaller size, longer, more rectilateral pronotum, form 

 of the tempora and many other characters.

Through the abrupt narrowing of the front before the eyes, the 

 antennae in this genus are less distant than usual, but there is no 

 tubercle properly speaking, and the form of the head differs only in 

 degree from that of the other Euplecti, resembling Bibloplectus and 

 Thesiastes in this respect, but with a much more robust body. 



Apothinus of Sharp does not differ from Thesium by any feature 

 mentioned in the description of that genus, but as the type is a 

 much larger insect than our representatives of Thesium, it may 

 actually be different. No mention of the structure of the proster- 

 num is made in the diagnosis of Apothinus, so that but little of 

 definite value can be said in regard to the extent of this relation- 

 ship. 



The basal foveae of the elytra in Thesium are three in number, 

 distinct, deep, circular and mutually rather distant, the first and 

 second from the suture transversely connected by a deep sulcus, 

 the second prolonged in basal fourth or fifth in an arcuate stria, 

 the third prolonged for a short distance in a broad and deep, gradu- 

 ally wider and shallower excavation, the sides of which are rather
