tral segments (four in Gibbium) ; the second, third and fifth longer 

 than the first and fourth ; the fourth sometimes very short. Legs 

 long, not contractile; trochanters in the axis of the thighs, very 

 long in Gibbium; thighs more or less clavate ; tibiae slender, with 

 two small or minute terminal spurs. Tarsi 5 jointed ; joints 1-4 

 decreasing in length ; fifth longer, but usually shorter than the first; 

 claws small, slender, simple, strongly divergent or divaricate. 



I have removed Hedobia and Eucrada from this subfamily and 

 placed them at the head of the Anobiiime. There is, I think, no 

 doubt that they fall naturally between the Ptininse and the typical 

 Anobiinae, but the points of divergence from the former are far 

 more numerous than the points of contact, and are generally in the 

 direction of the latter, which on account of its greater heterogeneity 

 is less disturbed by their reception. In the Classification, by Le- 

 Conte and Horn, the antenna? of Hedobia and Eucrada are said to 

 be inserted on the front. It would be more accurate to say that the 

 point of insertion is at the an tero- interior margin of the eye (slightly 

 more frontal in Eucrada) and really differs very little from its posi- 

 tion in the Anobiinae ; the apparent difference being largely due to 

 the fact that the front is not margined above the base of the antennae. 



In the European genus Dryophilus, belonging unquestionably to 

 the Anobiinse, the antennae are still more frontal in position, from 

 which it will be seen that too much stress should not be laid upon 

 this aberrancy. 



The antennae in Hedobia are it is true similar to those of Ptvius, 

 and the prothorax in both this genus and Eucrada is unmargined at 

 -ides; but on the other hand the antennae in Eucrada approach 

 rather Xyletinus and Vrilletta. of the Anobiinae, and in Gastrallus 

 of the latter subfamily the thorax is almost without side margin, 

 and in one species of Hadrobregmus is completely so. Further- 

 more, both Hedobia and Eucrada differ conspicuously from all our 

 genera of Ptininae in palpal formation ; in the apically bidentate 

 mandibles; in the absence of a prosternal process separating the 

 front coxae; in the subequal ventral segments, the fourth being 

 scarcely shorter than the third, and the first not narrowed by the 

 posterior coxae; in their non clavate femora; and finally, in the 

 stout tarsi, the terminal joint being broadly triangular with perfectly 

 divaricate claws.
