This species is allied to P. coeeinelUna, Gerst., but may be at once 

 distinguished by the four large round black dots on the thorax 

 which extend transversely and at even distances across its arcuate 

 disk. The thorax is at the same time more arcuate and with all 

 its angles more obtuse and round; it is, indeed, very similar in 

 shape to that of many CoccineUidae. The spots on the elytra are 

 more transverse and in general larger than the corresponding ones 

 in P. coccinellina ; this is especially true of the intermediate pair, 

 which nearly form a fascia ; the exterior spot of: these is straight 

 on its outer margin, and even produced a little as if to join the 

 outer subterrainal one, but it does not touch the reflexed edge. 



The seven species of Panomosa which have been described up to 

 the present time are readily distinguished by their markings. The 

 present species with P. pardalina and P. coccinellina have each 

 seven spots on each elytron, P. borneensis has six, P. undecimnotafa, 

 Frivaldsky, and P. cinglialensis, Grorh., have five spots, but the 

 latter has but ten joints to its antennae. P. sumatrensis, Gorh., has 

 no spots. 



These insects appear to me to be true mimics of the Cocclnellidse, 

 and that the resemblance is not merely accidental. P. Indiana so 

 well resembles some species of Leis or Caria, that it would easily 

 deceive a very good naturalist. Indeed in this insect the whole 

 body, especially the prothorax, has become completely Coccinellid. 

 It is true that those points of structure which are not so obvious, 

 e. g. the form of the antennas and prosternura, the absence of 

 abdominal fossae from the hind femora, &c., maintain their Endo- 

 myohid type.

Picea, nitida, protliorace transversa minute pvnctato, cequali, sulcis 

 basalihus concinne impressis, lateribus hand marginatis antice 

 angustatis, angulis anticis et posticis acutis, basi sinuato ; elytris 

 convexis, sparsim jjunctulatis, punctis discoidalibus in se.riebus 

 quinque haud regulariter digestis, ad apicem evanescentihus, 

 externe confusis, singulis maculis quatuor aurantiacis, una 

 basali, una subhumerali, una pone medium prope suturam, 

 una subapicali ; antennis dilute piceis, clava fusca. Long, 

 5'5 millim.

Eather larger and rounder and more convex than B. papuensis ; 

 the thorax more narrowed in front and wider behind, and so 

 forming a more even outline with the elytra than is the case in 

 B. papuensis ; the antennae are similar to those of that species, but 

 are thinner, with more linear joints, the apical joint is longer.
