48 MEMOIRS ON THE COLEOPTERA 



developed than in the larger female, and they therefore represent 

 two species, the male being the true Anomala cupricollis Chev., 

 and the female the form called coagulata by Bates, although the 

 elytra exhibit but few cloud-like spots, except about the external 

 edges of the elytra. Some other of the large Central American 

 species, such as Anomala megalia and pracellens of Bates, will also 

 enter the subgenus in all probability. 



Lamoana n. gen. 



The type of this genus and the only species known to me, is the 

 aberrant Mexican Anomala villosella of Blanchard, a specimen of 

 which taken by Wickham at Pte. de Ixtla, Morelos, is now at hand. 

 In the slender ascending mes-epimera, it is allied to the Strigo- 

 dermids. The mesosternum between the coxae does not have the 

 protuberant form seen in either Spilota or Strigoderma, being simply 

 rather wide and unusually convex, with the suture separating it 

 from the hairy metasternum distinct. It is peculiar in its pubescent 

 surface throughout above and beneath, the pubescence of the elytra 

 being an especially aberrant character in this part of the series. 

 The body is almost evenly oval and convex, the entire head and 

 pronotum not coarsely but deeply, evenly and very densely punctate, 

 the pronotum with a very fine basal bead, obsolete medially, less 

 than a third wider than long, with the sides almost evenly rounded 

 and moderately converging from base to apex, the latter deeply 

 sinuate. The punctate elytral striae are subequal and very close- 

 set as in Strigoderma, but they are much more shallow and the 

 second interval has the punctures very confused but only narrowly 

 along its axial line. The convex shining pygidium has long, coarse 

 silky pubescence and is feebly sculptured. The larger anterior 

 claw in the male is stout, arcuate and gradually obliquely pointed ; 

 on its upper surface there is, at a point but little beyond the middle, 

 a very short and almost bristle-like process, diverging from the 

 claw so slightly that the cleft is barely visible. The hind tibiae 

 are but very slightly surate. The body is about 8.5 mm. in length. 



Strigoderma Burm. 



This genus is exclusively North and South American and in- 

 cludes many species. I have assumed the Mexican Strigoderma
