248 CHRYSOMELID^E. 



margined with black. Elytra not deeply punctate-striate, the 

 punctures still finer posteriorly but visible, interstices flat, trans- 

 versely wrinkled at middle, opaque near apex, the markings 

 variable in size. Pygidium generally with an obscure brown 

 marginal spot and a central black spot at base ; prosternum 

 broadly produced at middle of anterior margin. 



Var. a. Thorax without spots ; elytra with three small black 

 dots (2 . 1), one on shoulders, one obliquely inwards between 

 third and fourth row of punctures and the third behind the 

 middle, midway between first and second spot (C. analis, 

 Oliv.). 



Var. b. Thorax with two transverse black spcts, placed widely 

 apart. 



Var. c. Thorax with two large transverse kidney-shaped 

 patches ; elytra with a transverse band at base and a large trans- 

 verse spot behind the middle black. 



Length 5-7 mm. 



Hab. Bengal : Nilgiris ; Coromandel ; Tranquebar. 



In well-marked specimens the sides and last segment of the 

 abdomen are flavous, middle portion black, and the pygidium with 

 a black spot at middle of base. 



434. Cryptocephalus quadratus, Suffr. Monoyr., Linn. JEnt. ix, 1854, 

 p. 66 ; id. t. c. xiv, 1860, p. 32. 



" $ . Pale fulvous ; head with three, thorax and elytra \vith two 

 black spots ; beneath black ; abdomen margined with red. 



"Head with short central deep groove at vertex, closely and 

 strongly punctured, as is also the clypeus ; a broad frontal and a 

 small round spot at base of each antenna black ; the latter pale 

 fulvous, scarcely half the length of the body, distinctly widened 

 terminally from beyond the fifth joint. Thorax remotely but 

 coarsely punctured, margins and a central line pale, edge of 

 posterior margin and two widely separated spots at middle black. 

 Scutellum triangularly elongate, black and shining. Elytra raised 

 round scutellum, epipleural lobes short but distinct ; surface regu- 

 larly punctate-striate, coarse anteriorly, intermediate rows finer 

 at middle, interstices slightly raised, finely wrinkled, less shining 

 than thorax, basal and sutural margins narrowly black ; the spots 

 large, transverse, the basal spot near margin obliquely placed 

 towards suture, equally distant from either margin, posterior spot 

 behind the middle, nearly as long as broad between second 

 and eighth rows of punctures. Pygidium black, finely silvery 

 pubescent margined with fulvous. Prosternum, middle of first 

 abdominal segment and margins at sides yellowish-red ; anterior 

 edge of prosternum broadly produced, hollow. 



" Length 4| mm. 



" Hub. Southern India. 



" Closely resembles C. analis, Oliv., but smaller and with 

 entirely different elytral sculpturing." (Suffrian.)
