TWO NEW BEETLES OF THE FAMILY MORDELLIDAE 



FROM ORCHIDS 



By Eugene Ray 



The descriptions of mordellid beetles lierein make available for 

 reference the names of two new species of Mordellistena taken in 

 the leaves of orchids. A previously described species [M. cattleyana 

 Champion^) has been collected from the flower of CatMeya sp. 

 The present paper extends the knoAvn habitat of the genus to include 

 the orchid genera Epidendrum and CaiUoga. 



Genus MORDELLISTENA Costa 



MORDELLISTENA EPIDENDRANA, new species 



This species may be separated from cattlexjana Champion by the 

 absence of the two traiisverse, fuscous, elytral fasciae, the broader 

 terminal segment of the maxillary palpi, and the diiferent number 

 of ridgelike rows of short black setae on the posterior tibiae and 

 tarsi. 



Length: 2.5 mm; including anal style, 3.2 mm. Elongate, sub- 

 parallel. Derm bicolored; head piceocastaneous (a narrow line 

 along occiput and a broad circular area along front fuscocastaneous 

 in female); pronotum flavocastaneous ; a vague cloud visible in 

 some specimens at center of base; scutellum f uscopiceous ; elytra 

 castaneous, with suture and lateral margins narrowly fuscous — in 

 the male the fuscous coloration includes the entire apical half of
