points of structure from the species of that geuus, as to induce me to 

 give it a distinct generic name, and I have created one in compliment 

 to its discoverer, who is working most energetically with a view to 

 give us a knowledge of the insect fauna of the isolated insular group 

 in which he is just now resident. 



The mandibles of this insect are simple, and rather short and 

 stout. The labrum is rather large, and its front margin is slightly 

 emargiuate. The labial and maxillary palpi are rather long and slen- 

 der, and are formed as in Ancliomemts. The eyes are small, not at all 

 prominent, and indistinctly facetted. The thoracic segments are 

 formed very much as in Anchomenus. The last three sutures of the 

 ventral segments are excessively deep ; the apical segment is rather 

 long, and not in the least truncate. The elytra are not sinuate near 

 the apex, and their apical portion is more elongate than in Ancho- 

 menus. The legs are rather short, but are formed as in Ancliomenus. 

 Fourth joint of the tarsi simple, its hind margin a little emargiuate. 

 The iinguiculi are simple. The scutellum but little visible. 



The points in which this insect departs from Anchomenus are, the 

 greater development of the after body in proportion to the head and 

 thorax, the feeble eyes, the very deep ventral sutures, and the elonga- 

 tion of the elytra at their extremity, and their accurate co-adaptatiou 

 with the elongate apical ventral segment. I think the genus should 

 be placed very near Ancliomenus, but the genus Gardiomera approaches 

 it in respect of the deep ventral sutures. It is possible that a know- 

 ledge of the trophi will reveal other differences from Anchomenus.
