252 LAMELLICOENIA. 



The head and thorax are black, opaque, the latter clothed with a very dense, erect, 

 and soft light-coloured pile. The elytra are pale reddish-brown, subopaque ; in one 

 example only (captured by Mr. Salvin at Chinautla) are they variegated with black — a 

 broad fascia behind the middle, and a second spot on each side near the tip of the 

 scutellum. The scutellum is like the thorax opaque, black, and coarsely shagreened. 

 The head, especially in the male, has the long, quadrate form and upturned edges of 

 the typical species ; and E. moreletiana is undoubtedly congeneric with E. mexicana. 



As in many species of Anomala, of the A. micans group, the sharp ascendent edge of 

 the mesosternal epimera rises in front of the shoulders of the elytra so as to be visible 

 from above. This feature shows the close relationship of those forms with Epectinaspis 

 and Strigoderma. An example from Duenas is figured. 



6. Epectinaspis ambigens. 



Phyllopertlias horticolm similis, sed thorace angustiore et antice gradatim attenuate ; clypeo ( $ ) sac angusto et 

 elongato-subquadrato, antice cum angulis rotundato margineque reflexo. Mger, capite thoraceque opacis, 

 hoc dense erecte piloso, elytris castaneo-rufis ; capite toto densissime connuenter punctato ; thorace medio 

 fortiter breviter dilatato, antice gradatim angustato, postice lateribus parallelis, dorso sicut in E. mexicana 

 convexo et juxta basin subito declivi, margine basali integro, supra punctato-alutaceo ; elytris grosse et 

 subconfuse punctato-striatis, sub callo humerali profunde impressis, margine laterali ( £ ) vix axupliato nee 

 incrassato ; abdomine nigro-aeneo, pygidio nitido, arcuatim striguloso, sparsim piloso. Mesosternum sat 

 latum et depressum, sed apice (juxta metasternum) paullo tumidum. Tibiae anticae bidentatae, posticas 

 haud suratae, grossissime elongato-punctatas. Mesosterni epimera paullo ascendentes et tumida nee acute 

 margin ata. 

 5 . Ungues exteriores 4 profunde fissi.

Hah. British Honduras, R. Sarstoon (Blancaneaux). Two female examples. 



The obtuse subascendent mesosternal epimera are unlike anything to be seen in other 

 species of Epectinaspis, where, if visible at all, they appear in a sharp carinated edge as 

 in many Anomalce. The convexity of the hind part of the thorax and the form of the 

 clypeus (which is no doubt more pronounced in the unknown male) show that the 

 species belongs to Epectinaspis. 



STEIGODERMA. 



Strigoderma, Burmeister, Handb. der Ent. iv. 1, p. 3X0 (1844); id. ibid. iv. 2, p. 514 (1855); 

 Lacordaire, Gen. Col. iii. p. 336 (1856). 



A genus, so far as at present known, peculiar to America, and ranging far into the 

 northern temperate zone, as well as throughout the intertropical region as far south as 

 Tucuman. It is well represented in Mexico and Central America ; and the numerous 

 species we have to add to the genus show a far wider range of sculpture, as well as form, 

 than was anticipated when the generic name was given. But, however diverse, they 

 resemble each other much more than they do any of the varied forms of Anomala, 

 and the tumid ascendent mesosternal epimera afford a good distinguishing character
