76 Psyche [Jime 



Known only from "Brazil." Two specimens were sent, both of 

 which are from Madeira-Mamore R. R. Camp No. 41. Neither 

 of the specimens differs in any way from the type as described. 



9. Ichnea humeralis Spinola var. irrita nov. (Plate 7, fig. 4.) 



Elongata, siibnitida; elytris sub-violaceis, vittis cluabus una laterali una discoidali 

 ad basim confluentibus -pallide flavis. — Long. 5.5-8.5 mm. 



Rio Madeira, Brazil; Madeira-Mamore R. R. Camps No. 41 

 and 43. Type and paratypes from the latter place. 



Differs from the typical form in having the lateral margins of the elytra narrowly 

 bordered with pale yellow, the pale margin usually extending to apical fifth, rarely 

 reaching only to about the middle of the elyti-al length. Ground color of the elytra 

 slightly v'ariable, usually dark violet, some times nearly black, rarely with a dis- 

 tinct coppery luster. 



Apparently an abundant species, to judge by the extensive series 

 taken by the expedition. Singularly enough there is not a single 

 example of the type form in the entire lot. 



10. Pyticera flavicoUis Gorham. (Plate 7, fig. 5.) 

 Pyticera flaricollis Gorh. Trans. Ent. Soc. Lond., 1877, p. 416. 



The original types of this species were taken at Ega and San- 

 tarem, Brazil, by Mr. Henry W. Bates. Herr Sigm. Schenkling 

 has since described a variety from Bolivia (Yungas de La Paz), to 

 which he has given the name siduralis. 



A single specimen of this rare and interesting species from Abuna, 

 Brazil, was sent me. The specimen is 9.5 mm. in length, being 

 somewhat larger than the types which are 6-8 mm. in length. 

 The specimen in some ways nearly agrees with the variety sidura- 

 lis, the length of which is given as 11 mm., and in which the suture 

 of the elytra from scutellum to the middle is yellowish red. The 

 specimen before me has the same part of a dull testaceous color, 

 being not at all conspicuous and in feeble contrast with the black 

 ground color. The head is uniformly yellowish red, the inflexed 

 elytral margin, the coxae and trochanters, the sides of abdomen 

 wholly, and the basal segments in part, yellow. The legs black, 

 with the exception of the front pair, which are rufo-piceous.
