RUTELIN.E IOI 



pygidium is uniformly punctured, loosely pubescent throughout and 

 without median impression. The absence of the male prevents me 

 from recording the length of the antennal club in that sex of rufo- 

 brunnea; in the female, at any rate, it does not differ sensibly in 

 form or proportion from that of Cotalpa. 



The genus Areoda MacL. is more closely allied to Cotalpa than 

 it is to Parareoda, having the antero-lateral elytral impression al- 

 most similar and the sculpture of the upper surface almost identical, 

 but the base of the prothorax is abruptly lobed medially and 

 the hind angles are very broadly rounded; the head and clypeus 

 are nearly similar, but the eyes are more developed ; the intermeso- 

 coxal process is much larger and is anteriorly protuberant. In 

 view of the close general similarity in habitus between Phalangogonia 

 and Cotalpa, I have sometimes thought that perhaps the singular 

 special modification of the labrum and mentum in the former genus, 

 might not be taxonomically so radical as considered by Lacordaire, 

 but it is at all events a very convenient criterion in classification and 

 I know of none other as a substitute. 



Rutela Latr. 



This genus, having an elongate-oval form of body and generally 

 very smooth, polished and more or less strikingly ornamented 

 integuments, has its principal focal centre in the West Indies, 

 though a number of species occur also in South America and Mexico. 

 One of the Cuban species occurs also in southern Florida and is 

 very well known in collections. The oral organs are of the usual 

 type in the preceding genera, the mentum feebly concave anteriorly; 

 the mandibles are bidentate externally; the prolongation of the 

 metasternum between the middle coxse, the suture being completely 

 obsolete, is unusually broad, narrowing to the very obtuse over- 

 hanging apex. The tarsi are slender, the claws simple and only 

 slightly unequal in size and the antennal club is moderate in both 

 sexes. Our single, but not truly native, species is the following: 



Body elongate-oval, convex, the elytra somewhat flattened medially, 

 highly polished throughout and completely glabrous below as well 

 as above, pale brownish-flavate in color, with complex black and 

 feebly submetallic spots and vittae; head moderate, minutely punc- 

 tate laterally, the clypeus triangular, with straight sides and rather 

 sharply bidentate, somewhat reflexed apex, its surface strongly and
