Indiana, Iowa (Keokuk), Texas (Galveston and El Paso) and 

 California (Lake Co). This common and apparently cosmopoli- 

 tan species has been thoroughly described by LaFerte, and may 

 always be recognized by the small double tubercle of the prono- 

 tum, which is not wanting in any specimen of the true JloraUs 

 which I have seen ; in some specimens the feeble depression be- 

 tween the tubercles is prolonged along the median line for a con- 

 siderable distance toward base. In the male the general form is 

 stouter, the head and prothorax especially being broader, and the 

 antennje apparently a little longer and thicker, but the mesostcrnum 

 and pronotal tubercle are not at all affected sexually. The mosi 

 remarkable external sexual difference relates to the form of 

 the pygi<lium, which, in the male, is vertical and strongly con- 

 vex, while in the female it is nearly flat, extremely oblique and 

 almost horizontal. It is not only probable that this is not 

 the MeJoe JloraJis of Linne, but quite possible that it may be dif- 

 ferent from the Anfhicus Jloralis of European authors, though 

 belonging to the same subgenus, for the length of the Euroix'.ui 

 insect as given by LaFerte* (3.0-3.5 mm.), is substantially greater 

 than that of the American representative, and LaFerte seems to 

 be very accurate and careful in his measurements. 



'2. II. enodis n. S]).— Stout, convex, anterior parts sliininj;, the elytra 

 polislied, dark riifo-testaceons, the nieta&terniun, abdomen and head blackish; 

 pronotuin blackisli anteriorly; elytra jticeous-black, gradually and indefinitely 

 paler toward base; autenure and lej^s dark brownish-rufous; femora darker; 

 pubescence decumbent, extremely short and sparse, the elytra also with ex- 

 ceedingly short remote and erect setic. Head moderate in size, thick, convex, 

 truncate and strongly, medially impressed at base, sub<iuadrate, as long as 

 wi(le; eyes moderately large and convex, about as long as and more prominent 

 than the tempora, the latter parallel; basiil angles broadly rounded; disk finely 

 but strongly, not densely punctate, the punctures intermingled with short 

 vermieiilate scratches, which become gradually dense and close toward the 

 sides; antennse not as long as the head and prothorax, very thick and sub- 

 moniliform, gradually and rather feebly incrassate, the penultimate joints 

 nearly as long as wide. Prothorax as wide as the head, fully as long avS wide, 

 narrowly rounded and \videst between apicjil fourth and fifth, the sides 

 thence rather strongly oblique and nearly straight to the subbasiil constriction ; 

 apex transversely arcuate; disk with an impressed fold parallel to the basixl 

 margin, which is continued obli(iuely upon the Hanks in a deep impression, 



■■'Accurate and miiuite measures of lengtli and w idth are one of the most 

 importiuit aids in identifications from descri))ti(>n. and more care should be 

 devoted to them than is usuallv the case.
