May, '09] ENTOMOLOGICAL XRWS. 233 



Described from two male and two female examples taken by 

 Mr. George Gray, the collector for the Wood's Holl Marine 

 Biological Laboratory, in Florida, and kindly sent to me for 

 study by Prof. E. B. Wilson of Columbia University. This 

 large showy insect seems to be strictly intermediate between 

 dorsalis White and gundlachi Guer. From the former it 

 differs most conspicuously by the alternated connexivum, and 

 from the latter by the unicolorous corium. In soine of the 

 examples the apex of the corium is distinctly infuscated, but 

 this may be owing to immaturity. 



Oncopeltus spectabilis n. sp. 



Closely allied to gutta H. S , but with the yellow markings of that spe- 

 cies replaced by orange-red. Antennae, rostrum, legs, mesosternum, 

 mesopleura anteriorly, a longitudinal vitta on the intermediate acetabu- 

 lae, sides and hind margin of the metapleura, apex of the venter, broad 

 hind margin and narrow edges and median line of the posterior lobe of 

 the pronotum, base and median vitta of the scutellum, a transverse vitta 

 on the corium broader on the costa, and the membrane black. Disk of 

 the membrane with a transverse white mark. Head scarlet; tylus black; 

 eyes and ocelli fuscous. Fourth and fifth ventral segments scarlet, with 

 a transverse blackish intermediate vitta. Antennae distinctly pilose ; 

 basal joint surpassing the tip of the tylus by at least one-half its length ; 

 second longest ; fourth scarcely shorter ; third rather more than twice the 

 length of the first. Length 10 mm. 



Described from one male taken by me at Kingston, Jamaica, 

 and recorded as O. gutta in my paper on the Jamaican Hemip- 

 tera. At the time of publishing that paper I had not seen the 

 real gutta and did not like to describe this form as new on 

 color characters alone. It is quite distinct from gutta in its 

 more hairy surface, the longer basal joint of the antennae, the 

 deep orange instead of yellow color, the scarlet head, the nar- 

 rower black vitta on the elytra and the absence of a black me- 

 dian spot on the anterior lobe of the pronotum. The extent 

 of the black markings may be variable in this species as it is 

 known to be in gutta. 



Ischnodemus slossoni n. sp. 



Closely resemblmgfaticus, but with the rostrum longer and the antennae 

 pale at base. Head less strongly punctured than m f aliens ; deep black, 

 scarcely sericeo-pubescent. Antennae rather slender, the apical joint 

 thicker than in the allied species ; pale rufo-testaceous at base ; third
