i8o MEMOIRS ON THE COLEOPTERA 



Pancota Csy., (1. c., sec., p. 345) is a Myrmedoniid and was redescribed 

 (Mem. Col., I, p. 136), under the name Dolosota. 



Sibiota Csy., (1. c., sec., p. 350) is a subgenus of the Myrmedoniid 

 Sipalia Rey. 



Autalia Mann. 



Closely resembles some of the Falagrise in general habitus but 

 probably not closely related phylogenetically. There are a number 

 of species in our Pacific coast region, but thus far none has come to 

 light in eastern North America; the following are represented for 

 the most part by good series in my cabinet: 



Autalia copiosa n. sp. Large and notably stout, convex, strongly- 

 shining, black, the abdomen basally and the elytra feebly rufescent, 

 the legs pale; punctures extremely fine and sparse throughout, not 

 asperate except on the fifth tergite, where they are closer and asperate, 

 the three deep tergitical impressions closely granulo-reticulate, crossed by 

 three strong carinse and limited at each side by a smooth elevated space; 

 pubescence sparse but rather long, grayish; head evidently wider than 

 the prothorax, as long as wide, semicircularly rounded behind the eyes, 

 which are moderately prominent; antennae black, long and very heavy, 

 also gradually and distinctly incrassate, the first three joints equal in 

 length, fourth nearly one-half longer than wide, fifth a little shorter 

 though elongate, sixth as wide as long, the tenth a third wider than long, 

 the last much shorter than the two preceding; prothorax barely as long 

 as wide, widest at two-fifths from the apex, where the sides are rather 

 prominently rounded, thence strongly converging to the apex and very 

 feebly converging and subsinuate to the base, the median sulcus distinct 

 anteriorly but obsolete basally, where the four longitudinal impressions 

 are well developed; elytra large, slightly wider than long, feebly swollen 

 apically, rather more than twice as wide as the prothorax and three-fourths 

 longer, the two basal impressions on each distinct; abdomen narrower 

 than the elytra and, at base, three-fourths as wide, feebly swollen apically. 

 Length 1.85-2.4 mm.; width 0.5-0.68 mm. California (Sta. Cruz Co.). 



The large series before me displays very little variability except 

 in size. This species differs from elegans Csy., in its stouter form, 

 darker coloration, stouter but less distally incrassate antennae, 

 relatively somewhat larger prothorax and less parallel abdomen, 

 with the carinse crossing the impressions much more developed. 



Autalia truncatula n. sp. Moderately stout and convex, strongly 

 shining, the coloration as in copiosa; punctures minute and sparse, 

 scarcely at all asperulate except on the abdomen apically and toward the 

 base of the pronotum, where the punctures take the form of large sub- 

 elongate granules; abdominal impressions as in the preceding, except 

 that the lateral carinse are not fine, like the medial, but very broad and 

 flat; pubescence sparse though notably long and bristling; head slightly
