TRYPAN AUS.—TERETRIUS. 231 
distinctly elongate. In both sexes the elytra are narrowed behind, so that there is no 
interruption in the outline between them and the long pygidium; the latter in the 
female is nearly one third of the length of the insect. 
16. Trypanezus parallelus, sp.n. (Tab. VI. figg. 21 3, 229.) 
3. Cylindricus, angustatus, parallelus, niger, nitidus; fronte impressa, rugoso-punctata; capite minute 
transverso-strigosa; rostro excavato, apice rufo, reflexo; pronoto stria laterali integra, parce punctato, 
ante scutellum depresso, levi, unifoveolato; elytris punctulatis; pygidio brevi, aspere punctato, flavo- 
piloso; prosterno subparallelo, apice truncato, laterali invalide striato; mesosterno brevi, antice immar- 
ginato; metasterno longissimo, medio longitudinaliter sulcato, sparse punctulatis; tibiis anticis 5-, 
intermediis 6-dentatis, posticis brevibus, basi angulatis. 
Q. Fronte leviter impressa ; pygidio elongato, obtuse producto. Long. 3 millim. 
Hab. Guatemata, Capetillo (Champion). 
There is one singular character in this species: in front of the scutellum for about a 
fourth part of the length of the thorax there is an absence of punctures and in their 
place a longitudinal impression, in the anterior part of which is a well-marked fovea. 
This character alone has enabled me to associate the sexes, as it is common to both 
male and female. 
The metasternum in 7’. parallelus is more than seven times as long as the mesosternum. 
Three examples, two males and one female. 
17. Trypanezus angustatus, sp.n. (Tab. VI. figg. 23 3, 24 9.) 
é. Cylindricus, angustatus, parallelus, niger, nitidus; fronte depressa, inter oculos tuberculata; rostro rufo, 
laterali parallelo, apice trigono, reflexo, in medio carinato; pronoto antice retuso, truncato, stria pone 
oculos interrupta, angulis rufis, ante scutellum parce punctato; elytris sparse punctulatis; propygidio 
pygidioque dense sat grosse punctatis; prosterno modice angustato, parallelo, sulcis marginalibus validis 
antice junctis; mesosterno stria integra, lobo obtuso; metasterno longissimo, in medio (antice valide, 
medio tenuiter, postice modice) longitudinaliter sulcato, subtilissime at sparse punctulatis; tibiis anticis 
5- vel 6-, intermediis valide 5-dentatis, posticis brevibus, basi subangulatis. 
9. Fronte depressa; rostro apice truncato, immarginato; pygidio conico, modice producto, subtus plano. 
Long. 3 millim. 
Hab. Guatemata, Capetillo, Calderas 6000 feet (Champion). 
There is no salient character in this species, as in the last, whereby to associate the 
sexes; but I have every reason to believe that I have rightly united them. The sulcus 
in the metasternum is alike in both sexes, as they are here regarded, viz. very wide for 
about two thirds of its length, then narrowing at the middle and widening out again 
towards the base. 
Six examples and some fragments.

This genus is represented in our catalogues by about twenty-five species, but 
doubtless many more remain to be discovered. Its members are widely spread, though
