SOME EA R WIGS FROM GA UTEMA LA—CA UDELL. 175 



broadly concave, truncate, the apex obscurely bituberculate; last ven- 

 tral segment transverse, rounded. Forceps very short and stout, tri- 

 angular basally, nearly contiguous and curved decidedly upwards, but 

 onl}" slightly inwards and that only at the tip. 



Length. — Body, without forceps, 5 nun.; forceps, 0.5 mm. 



Type-specimen.— C&t No. 10369 U.8.N.M. 



This insect presents characters, such as the many jointed antenna^, 

 smooth abdomen, etc., not in accord with those of the genus LoI/ku 

 but for the present I have preferred to place it questionably in that 

 genus. 



"This was beaten from leaves of recently felled trees in a new clearing at the 

 mouth of the Rio Dulce, about two miles from Livingston." 



SPHONGOPHORA PYGMAEA Dohrn. 



Four males, 3 females, C'acao, Trece iVguas, Alta Vera Paz, April 

 2, 5, 20, and 21. 



One of these specimens, a male taken April 2, represents a variety 

 ditiering from the typical form in the shape of the forceps, which are 

 uniforml}' bowed instead of nearly straight, and are almost unarmed 

 on the inner margin. One of the females has the elytra and wings 

 unicolorousl}' black. 



OPISTHOCOSMIA AMERICANA Bormans. 



Four males, 2 females, 3 immature specimens, Cacao, Trece Aguas, 

 Alta Vera Paz, April 11 to 27. 



The females sometimes have the wings conspicuously marked bv a 

 3'ellow spot, and sometimes the spot is almost entirel}^ absent. The 

 forceps of the male are sometimes shaped as shown in Bornmns's 

 original figure, but in three of the four representatives of that sex 

 now before me the forceps are tubercled about as prominently as 

 in Bormans's figure but are nearly straight, not so sinuate, in this 

 respect approaching the O. anomaJa of Kehn. 



"Running on brush. Not uncommon."
