20 MR. J. S. BALT ON SOME SPECIES OF GALERUCIN^. 



Hah. Type, Sumatra, Java ; var. A, Celebes, Grilolo, Floras ; 

 var. B, C, and D, Java ; var. E, Java, Philippines, Lombock ; 

 var. r, Ceylon ; var. Gr, Celebes. 



The above species is very nearly allied to A. coffecB^ Hornst., 

 agreeing closely in form and structural characters. The head in 

 the male of the present insect is narrow and the eyes are larger and 

 more prominent, and the apical surface of the intermediate lobe 

 of the anal segment of the abdomen is slightly concave instead 

 of plane. A. hicolor, however, although extremely variable in 

 coloration, always has the lower edge of the clypeus alid the 

 entire labrum concolorous with the upper face ; in A. coffece, on 

 the contrary, these parts are nigro-piceoua or black. 



29. AuLACOPHOEA NiGEiVESTis, Boisd. Voy . de VAstrol. p. 548. 

 Subelongata, postice paullo ampliata, convexa, fulva, nitida; tibiis apice, 



tarsis .mtennarumque articulis interraediis piceis ; abdomine elytrisque 

 nigris, his seneo tinctis ; thorace lateribus a basi fere ad apicem 

 rectis, disco sat fortiter transversim sulcato, sulco utrinque magis 

 distincte impresso. Long. lin. 

 Mas. Abdominis segmento anali trilobato, lobo intermedio alteris lon- 

 giore, transverso-quadrato, piano, apice truncate. 



Hah. Fiji Islands, a single specimen. 



Antennae nearly equal to the body in length, slender, filiform. 

 Thorax nearly twice as broad as long ; sides straight and parallel, 

 obliquely converging near the apex. Elytra narrowly oblong, 

 slightly dilated posteriorly, convex, distinctly punctured. Ex- 

 treme apex of the abdomen piceous. 



30. AuLACOPHORA DoWNESi. Ovata, postice ampliata, nigra, nitida, 

 capite, thorace, scutello pedibusque flavis ; thorace lateribus ante 

 medium obtuse angulatis, disco modice transversim sulcato; elytris 

 tenuiter punctatis, plaga magna basali, trigonata, communi, flava. 

 Long. 2f-3 lin. 



Mas. Abdominis segmento anali trilobato, lobo intermedio late oblongo- 

 quadrato, piano. 



Fcem. Abdominis segmento anali apice sinuato. 



Hah. India, Bombay {Dr. Ezra Downes). 



Antennas filiform. Thorax about one half broader than long ; 

 sides obtusely angulate before the middle, nearly straight pos- 

 teriorly ; upper surface transversely sulcate, the sulcation less 

 deeply impressed than in most other species of the genus. 

 Elytra dilated posteriorly, moderately convex, very finely punc- 

 tured.
