17. T? ichopteryx immature/,. N. 



T. prsecedenti similis, differt tamen colore supra seneo-testacea 

 subtus testacea, antennarum art. 3-11 nigrescentibus differt etiam, 

 corpore crassiore, magis quadrato, capite paulo majore, thorace mi- 

 nus convexo, parum ampliore, elytris abdomen totum vel fere to- 

 tum obtegentiis. Pedes, antennse etc. omnino prascedentis. Long, 

 corp. | lin. 



In prsecedentis societate specimina nonnulla legi. 



Of somewhat the appearance of an immature individual of the 

 former but sufficiently distinct to be formed into a new species. The 

 insect is altogether of a different appearance imparted to it by the 

 greater general plumpness of the body, the larger head, the less 

 convex but at the same time possibly still ampler thorax, the alto- 

 gether more quadrated shape, etc. The remark regarding the exact 

 number of abdominal segments left uncovered by the elytra, applies 

 to this and all other species as well. The present one has generally 

 the last two segments uncovered. 



18. Trichopteryx mvisibilis. N. 



T. ovata, subdepressa, subparallela, pilosa, supra obscure senea. 

 subtus picea, pedibus, abdomine, antennis oreque testaceis, Long, 

 corp. vex \ lin. 



Thorax amplus, elytris sesqui minor, convexus, angulis pos- 

 ticis humeros vix superantibus. Elytra oblonge quad rata 

 angulis rotundatis, subdepressa, truncata, abdomen totum vel fere 

 totum obtegentia. Coxse posticse approximatee. Tarsi typicis 

 minus elongati, art. 3° prsecedentibus haud multo longiore. 



Cum T, cursiiante victitat ; frequenter legi. 



A very pretty and very distinguished species. Its most striking 

 peculiarity consists in the posterior coxse which are as little distant 

 from e ach other as those of the anterior legs, and almost touch 

 each other, and also in the shortness of the tarsi. The head with 

 the antennae, the mesosternum, the tibiae, which are incrassated in 

 the middle, the posterior coxae with regard to the enlargement are 

 quite typical. However, the thorax and elytra differ again from 

 those of T, cursitans, (which in every respect may be looked upon
