1889.] COLLECTED IN VENEZUELA. 287 



the frontal elerations strongly raised, narrowly transverse ; clypeus 

 triangular ; terminal joint of the palpi acutely pointed ; antennae 

 black, the basal four joints fulvous ; thorax transverse, about one 

 half broader than long, strongly narrowed at the base, the angles 

 not produced, the surface with an obsolete oblique depression at each 

 side, very minutely punctured when seen under a strong lens : elytra 

 widened towards the middle, extremely closely punctured, the punc- 

 tuation consisting of small and still smaller punctures; each elytron 

 with the following black spots — one on each shoulder, three placed 

 transversely across the middle (the centre spot on the sutural margin), 

 four slightly larger spots below the middle forming a semicircle, and 

 one at the extreme apex of each elytron. 



Colonia Tovar. 



This species forms another addition to those constituting the 

 genus Malucorhinus described by myself in the ' Biologia Centrali- 

 Americana,' from all of which it differs in the number and position 

 of the elytral spots : the thorax in all is posteriorly narrowed, the 

 tibiae have a minute spine (sometimes almost invisible), the first joint 

 of the posterior tarsi is as long as the following joints together, the 

 claws are appendiculate, and the anterior coxal cavities are open. In 

 general appearance the species of this geiuis resemble those of the 

 genus Diabrotica, and seem to inhabit principally Central America. 



LOCHM-EA TROPICA, n. Sp. 



Broadly ovate, black ; above dark fuscous ; head and thorax 

 finely rugose ; elytra with the sutural and lateral margin and two 

 narrow longitudinal costse testaceous. 



Length 2k lines. 



Head finely rugose, the sides of the vertex and the clypeus tes- 

 taceous ; labrum black, shining; antennae about half the length of the 

 body, black, the third joint the longest ; thorax short and transverse, 

 narrowed at the middle, the angles tuberculate, the sides rounded 

 at the middle, the surface transversely depressed, finely rugose, 

 fuscous, the anterior and posterior margins paler ; scutellum truncate 

 at its apex, nearly black, finely rugose ; elytra broader than 

 the thorax, widened below the middle, rather convex, fuscous ; the 

 narrowly raised sutural and lateral margins, and two equally narrow 

 longitudinal costse at the middle of the disk and not quite extending 

 to the apex, testaceous, the interstices everywhere finely rugose and 

 wrinkled ; legs black, unarmed ; claws bifid ; the anterior coxal 

 cavities open. 



Colonia Tovar. 



This species has entirely the appearance of an Adimonia, but the 

 open coxal cavities would place the insect in Weise's genus Loehmcea. 



SCHEMATIZA FTJNEREA, U. Sp. 



Elongate, parallel, black ; the terminal joints of the antennae 

 fulvous ; the entire upper surface finely rugose, opaque ; elytra with 

 faiut traces of lighter bands at the sides.
