to such forms as the genus Limnichites, which were included in 

 the same table, it is altogether wrong. 



Lichminus Csy. 

 Limnichus (subgen. Lichminus Csy.), olim. 



This genus is very well characterized by the broad unimpressed 

 prosternum, broad flat hypomera, wholly devoid of the usual shining 

 inner margin so developed in Pelochares and distinct even in Lim- 

 nichodertts, by the unusually large equilatero-triangular scutellum 

 and rather long antennae, in which feature as well as the non-sulcate 

 prosternum it is allied to Pelochares, being the only close approach 

 to that European genus occurring in North America; but it differs 

 from Pelochares in the formation of the side margins of the prothorax, 

 the fine reflexed edge continuing here to the apex, while in that 

 genus it terminates anteriorly in a fine prominent angle at some 

 distance behind the thoracic apex. The prosternal episterna are 

 shorter, with the anterior angle simple and moderately acute, not 

 somewhat produced as it is in Pelochares. We know as yet but a 

 single species definable as follows: 



Evenly elongate-oval, gradually sharply acuminate behind, strongly 

 convex, black, rather feebly shining, the vestiture decumbent, 

 moderately short, not dense, coarse and almost uniformly fulvo- 

 cinereous; head evenly convex, strongly micro-reticulate, the very 

 fine feeble punctures thereby rendered indistinct; prothorax short, 

 with strongly converging and nearly straight sides, the apical angles 

 not or scarcely produced from above, the usual basal lobe rather 

 short, wider than usual, the median line not at all impressed, the 

 punctures minute and sparse, not stronger or denser laterally; elytra 

 more than a fourth longer than wide, the sides evenly rounded, grad- 

 ually converging and less arcuate to the acutely ogival apex, widest 

 well before the middle, the micro-reticulation relatively very coarse 

 but feeble, the punctures sparse, extremely fine, scarcely more than 

 scars marking the attachment of the hairs; abdomen shining, feebly 

 micro-reticulate, rather long, obtusely acuminate and only slightly 

 convex, very finely, evenly, not densely punctate, the last segment 

 more coarsely and closely throughout though very shallowly and 

 with somewhat longer fine hairs. Length 1.65-1.8 mm.; width 

 0.85-0.95 mm. California (Hoopa Valley, Humboldt Co.). [Lim- 

 nichus (Lichminus) tenuiconiis Csy., Ann. N. Y. Acad., 1890, p. 

 155] tenuicornis Csy. 



The three specimens in my collectio'h are very uniform and exhibit 

 no variability.
